Monitoring of mechanical sugarcane harvesting through control charts

ABSTRACT Statistical process control in mechanized farming is a new way to assess operation quality. In this sense, we aimed to compare three statistical process control tools applied to losses in sugarcane mechanical harvesting to determine the best control chart template for this quality indicator. Losses were daily monitored in farms located within Triângulo Mineiro region, in Minas Gerais state, Brazil. They were carried over a period of 70 days in the 2014 harvest. At the end of the evaluation period, 194 samples were collected in total for each type of loss. The control charts used were individual values chart, moving average and exponentially weighted moving average. The quality indicators assessed during sugarcane harvest were the following loss types: full grinding wheel, stumps, fixed piece, whole cane, chips, loose piece and total losses. The control chart of individual values is the best option for monitoring losses in sugarcane mechanical harvesting, as it is of easier result interpretation, in comparison to the others.

Repercussões pulmonares após isquemia hepática parcial e reperfusão: modelo experimental

OBJETIVO: Descrever um modelo experimental de lesão de isquemia/reperfusão hepática com manifestações sistêmicas, representadas pelo envolvimento pulmonar, que possa ser utilizado por aqueles que pretendem compreender esse fenômeno. MÉTODOS: Ratos Wistar machos (200-250g) foram usados. Quatorze foram alocados em dois grupos, sendo G1 com oito submetidos somente à laparotomia e G2, seis à isquemia e reperfusão hepática. As funções hepática (aminotransferases séricas, respiração mitocondrial, histologia) e pulmonar (teste do azul de Evans) foram analisadas. RESULTADOS: houve diferença estatística significativa entre G1 e G2 ao se comparar valores de AST (24,3 ± 108 e 5406 ± 2263), ALT (88,5 ± 28,5 e 5169 ± 2690), razão de controle respiratório (3,41 ± 0,17 e 1,91 ± 0,55) e relação ADP/O (1,93 ± 0,03 e 1,45 ± 0,27), lesões histológicas (necrose, células inflamatórias, hemorragia, microesteatose) e teste do azul de Evans (194,31 ± 53 e 491,8 ± 141). CONCLUSÃO: O modelo mostrou-se útil para o estudo de lesão de isquemia/reperfusão hepática.

Avaliação dos Níveis Séricos de Leptina em Mulheres Portadoras da Síndrome dos Ovários Policísticos

Objetivos: verificar os níveis de leptina em pacientes com síndrome dos ovários policísticos (SOP) e suas relações com a testosterona, o estradiol, o FSH e a insulina. Métodos: estudo transversal realizado com 40 pacientes portadoras de SOP, divididas em dois grupos, de acordo com o seu índice de massa corporal (IMC): Grupo I (n = 20): pacientes obesas (IMC >28 kg/m²) e Grupo II (n = 20): pacientes não-obesas (IMC <28 kg/m²). Resultados: foi observada diferença significativa na relação glicemia/insulina entre os dois grupos (p=0,043). Os níveis de leptina se mostraram fortemente correlacionados com o IMC (p<0,001). Verificou-se que, eliminado o efeito do IMC, por meio de análise de regressão multivariada, a dosagem da insulina (p=0,194), do FSH (p=0,793), das testosteronas total (p=0,441) e livre (p=0,422), e a relação glicemia/insulina (p=0,166) não influenciaram a concentração de leptina. Entretanto, observou-se uma correlação entre as concentrações de leptina e de estradiol (p=0,043). Conclusão: existe correlação entre os níveis de leptina, o IMC e as concentrações de estradiol, em mulheres portadoras de SOP.

Efeitos da associação estro-androgênica em mulheres na pós-menopausa

OBJETIVO: avaliar os efeitos da associação de estrogênios e androgênios sobre a qualidade de vida e a sexualidade de mulheres durante o climatério. MÉTODOS: foram incluídas 96 pacientes com sintomas vasomotores e disfunção sexual na pós-menopausa. As mulheres foram aleatoriamente divididas em três grupos de tratamento com 32 pacientes cada: placebo, estrogênios conjugados eqüinos (0,625 mg por dia) e associação de estrogênios conjugados eqüinos (0,625 mg por dia) e de metiltestosterona (2,5 mg por dia). O tratamento foi realizado por três meses. A avaliação da qualidade de vida e da sexualidade foi realizada por entrevista usando o Questionário de Saúde da Mulher (QSM) e o Questionário Simplificado sobre Sexualidade, antes e após o tratamento. Alguns parâmetros do risco cardiovascular, o eco endometrial e a toxidade hepática foram avaliados. Para análise dos dados aplicou-se o teste ANOVA, seguido pelo teste post hoc de Fisher e teste de Shapiro-Wilk. RESULTADOS: houve melhora nos parâmetros do QSM nos grupos que receberam estrogenioterapia isolada e associada ao androgênio em comparação ao grupo placebo. Entretanto, não houve diferença entre os três grupos em relação às questões referentes aos sintomas somáticos. A associação estro-androgênica foi superior ao estrogênio isolado nas questões relacionadas com função sexual (média da pontuação: 64 vs 67; p<0,05) e humor deprimido (média da pontuação: 75 vs 80; p<0,05). No grupo que recebeu a terapia estro-androgênica, houve redução do colesterol total (212±42 e 194±43, antes e após o tratamento, respectivamente) e do HDL-colesterol (56±16 e 48±14, antes e após o tratamento, respectivamente), bem como discreto aumento do eco endometrial (4,7±2,3 e 5,5±2,3 antes e após o tratamento, respectivamente). Não foi constatada alteração significante das enzimas hepáticas entre os grupos, durante o período de estudo. CONCLUSÕES: a associação estro-androgênica resultou em melhora na qualidade de vida e nos distúrbios sexuais. Este efeito foi superior à estrogenioterapia isolada e ao placebo. O efeito do tratamento estro-androgênico foi mais marcante nos itens de humor deprimido e de função sexual no questionário QSM.

Prognóstico obstétrico de pacientes portadoras de diabetes mellitus pré-gestacional

OBJETIVO: Avaliar as alterações epidemiológicas, de perfil clínico e de prognóstico obstétrico em pacientes portadoras de diabetes mellitus pré-gestacional. MÉTODOS: Estudo retrospetivo (coorte) de todas as gestações simples, com diagnóstico de diabetes prévio que foram seguidas num centro com apoio perinatal diferenciado entre 2004 e 2011 (n=194). Analisaram-se tendências relacionadas com dados demográficos e variáveis clínicas maternas, dados de indicadores de cuidados pre-concepcionais e durante a gravidez, e de controle metabólico. Dados do parto como a idade gestacional (IG) do parto, via do parto e peso do neonato foram variáveis também estudadas. RESULTADOS: A frequência global de diabetes prévia, durante o período estudado, foi de 4,4 por mil, não se verificando variações significativas durante o período de estudo. Os casos de diabetes tipo 2 permaneceram constantes. Em 67% dos casos o parto foi de termo (máximo de 80% em 2010 - 2011), registrou-se uma redução significativa dos partos por cesárea eletiva (p=0,03) e na incidência de neonatos considerados grandes para a IG (p=0,04) ao longo dos anos em estudo. Apesar dos bons resultados relacionados com o controle metabólico ao longo da vigilância da gravidez não foi registrada nenhuma melhora ao longo do tempo. Da mesma forma a proporção de gestantes diabéticas com avaliação pre-concepcional permaneceu pouco animadora. CONCLUSÕES: O seguimento de gestantes portadoras de diabetes mellitus em unidades multidisciplinares parece permitir um ajuste metabólico tão precoce quanto possível, de forma a conseguir melhorar o prognóstico obstétrico. A melhora nos cuidados pré-concepcionais continua sendo um desafio.

Internal quality control indicators of cervical cytopathology exams performed in laboratories monitored by the External Quality Control Laboratory

PURPOSE: To evaluate the impact of continued education provided by an external quality control laboratory on the indicators of internal quality control of cytopathology exams.METHODS: The internal quality assurance indicators for cytopathology exams from 12 laboratories monitored by the External Quality Control Laboratory were evaluated. Overall, 185,194 exams were included, 98,133 of which referred to the period preceding implementation of a continued education program, while 87,061 referred to the period following this intervention. Data were obtained from the Cervical Cancer Database of the Brazilian National Health Service.RESULTS: Following implementation of the continued education program, the positivity index (PI) remained within recommended limits in four laboratories. In another four laboratories, the PI progressed from below the limits to within the recommended standards. In one laboratory, the PI remained low, in two laboratories, it remained very low, and in one, it increased from very low to low. The percentage of exams compatible with a high-grade squamous intraepithelial lesion (HSIL) remained within the recommended limits in five laboratories, while in three laboratories it progressed from below the recommended levels to >0.4% of the total number of satisfactory exams, and in four laboratories it remained below the standard limit. Both the percentage of atypical squamous cells of undetermined significance (ASC-US) in relation to abnormal exams, and the ratio between ASC-US and intraepithelial lesions remained within recommended levels in all the laboratories investigated.CONCLUSION: An improvement was found in the indicators represented by the positivity index and the percentage of exams compatible with a high-grade squamous intraepithelial lesion, showing that the role played by the external quality control laboratory in providing continued education contributed towards improving laboratory staff skills in detecting cervical cancer precursor lesions.

Treatment of low-risk gestational trophoblastic neoplasia comparing biweekly eight-day Methotrexate with folinic acid versus bolus-dose Actinomycin-D, among Brazilian women

PURPOSE: To compare two single-agent chemotherapy (ChT) regimens evaluating, in first-line treatment, response and side effects and, in final single-agent treatment, the outcomes, among Brazilian patients with low-risk gestational trophoblastic neoplasia (GTN), according to International Federation of Gynecology and Obstetrics (FIGO) 2002. METHODS: Retrospective analysis of two concurrent cohorts with 194 low-risk GTN patients: from 1992 to 2012, as first-line treatment, 115 patients received 4 intramuscular doses of methotrexate alternated with 4 oral doses of folinic acid (MTX/FA) repetead every 14 days and, since 1996, 79 patients received an endovenous bolus-dose of actinomycin D (Act-D), biweekly. At GTN diagnosis, patient opinion was taken into consideration when defining the initial single-agent ChT regimen, and when there was resistance or toxicity to one regimen, the other drug was used preferentially. This study was approved by the Irmandade da Santa Casa de Misericórdia de Porto Alegre Ethical Committee. RESULTS: Both groups were clinically similar (p>0.05). In first-line treatments, frequency of complete response was similar (75.7% with MTX/FA and 67.1% with bolus Act-D); the number of ChT courses -median 3 (range: 1-10) with MTX/FA and 2 (range: 1-6) with bolus Act-D - and the time to remission -median 9 weeks (range: 2-16) with MTX/FA and 10 weeks (range: 2-16) with bolus Act-D) - were not different between the groups. In both groups, first-line side effects frequency were high but intensity was low; stomatitis was higher with MTX/FA (p<0.01) and nausea and vomit with Act-D (p<0.01). Final single-agent ChT responses were high in both groups (94.8% with MTX/FA and 83.5% with bolus Act-D; p<0.01) and 13% higher in the group initially treated with MTX/FA. Rates of hysterectomy and of GTN recurrence were low and similar. No patient died due to GTN. CONCLUSION: The two regimens had similar first-line ChT response. Final single-agent response rates were high and similar in both groups but the final single-agent remission rate was higher in the MTX/FA group.

Estudo sobre a ocorrência de fungos e aflatoxina B1 na dieta de bovinos leiteiros em São Paulo

A qualidade da dieta ofertada às vacas em lactação é uma preocupação dos agentes de saúde devido à possibilidade da detecção de micotoxinas prejudiciais a saúde humana e animal. Os objetivos do trabalho foram avaliar o perfil da micobiota, determinar a atividade de água (Aa) e a ocorrência natural de aflatoxina B1 (AFB1) em dietas ofertadas a vacas em lactação de fazendas leiteiras no estado de São Paulo, Brasil. As amostragens das dietas foram realizadas diretamente dos cochos de lote de 15 vacas, em dois dias consecutivos com intervalos de 24h e a cada 15 dias, perfazendo um período de 45 dias de amostragens por fazenda. A purificação e determinação de AFB1 foram realizadas em colunas de imunoafinidade e Cromatografia Líquida de Alta Eficiência (CLAE). O estudo da micobiota presente nas amostras das dietas (288) revelou que as leveduras foram predominantes em todas as dietas (83,97 a 99,98%). Foram isolados 15 gêneros de fungos filamentosos, com os gêneros Aspergillus spp (20,09%), Fusarium spp (14,16%) e Penicillium spp (11,48%) os mais prevalentes. As contagens de Unidades Formadoras de Colônias por grama de alimento (UFC. g-1) variaram de 102 a 1011. A atividade de água das amostras variou entre 0,91 a 0,98. Foi detectada a presença de AFB1 em 31,44% das amostras com teores entre 1,68 a 194,51μg.kg-1. Medidas de boas práticas de produção, estocagem e utilização devem ser tomadas para diminuir a ocorrência de AFB1 nas dietas ofertadas às vacas em lactação.

Plantas aquáticas e nível de infestação das espécies presentes no reservatório de Bariri, no Rio Tietê

O monitoramento da vegetação aquática permite avaliar a evolução das comunidades e determinar o potencial de danos associados a essas populações. O objetivo do trabalho foi identificar as plantas aquáticas e os níveis de infestação de cada espécie, presentes no reservatório de Bariri. Foram avaliados todos os focos de vegetação aquática presente na represa (194 pontos), e os pontos foram demarcados com um aparelho de GPS. As plantas foram identificadas e realizou-se uma estimativa visual do valor geográfico do ponto (tamanho da área) e a distribuição proporcional das plantas no foco de infestação. Foram encontradas 15 espécies de plantas aquáticas vegetando na represa de Bariri. Considerando que as principais espécies ocorreram com níveis de infestação acima de 10%, as mais importantes foram: Brachiaria mutica (27,0% da área e 97,4% de freqüência), B. subquadripara (22,7% da área e 96,9% de freqüência), Eichhornia crassipes (13,8% da área e 85,6% de freqüência) e Typha angustifolia (16,7% da área e 72,7% de freqüência). Outra espécie que pode ser destacada e que apresentou um bom potencial de infestação foi Enidra sessilis, que ocorreu em 8,9% de ocupação na área vegetada e com 76,3% de freqüência.

Upland rice yield as affected by previous summer crop rotation (soybean or upland rice) and glyphosate management on cover crops

The appropriate chemical management of cover crops in no-tillage aims to obtain greater benefits with its employment in agricultural systems. The objective of this study was to assess upland rice yield as affected by the previous summer crop, species and desiccation timing of cover crops by glyphosate. Sown cover crops were sown (November 2007), followed by rice in half of the experimental area and soybean in the other half (November 2008). After the harvesting of these crops, the same cover crops were sown again (March 2009) and followed by upland rice in the total area (November 2009). The experiment consisted of the combination of five cover crops (fallow, Panicum maximum, Brachiaria ruziziensis, B. brizantha and Pennisetum glaucum), four desiccation timings (30, 20, 10 and 0 days before rice sowing), and two antecedents of the summer crop (rice or soybean) under no-tillage system (NTS), plus two control treatments at conventional tillage system (CTS). Cover crops significantly affect rice grain yield and its components. There is a significant tendency to highest yield when cover crop desiccation is conducted farther from the rice sowing date (from 2,577.1 kg ha-1 - desiccation at rice sowing to 3,115.30 kg ha-1 - desiccation 30 days before rice sowing). Soybean as an antecedent of summer crop allows better upland rice yield (3,754 kg ha-1) than rice as an antecedent of summer crop (2,635 kg ha-1); fallow/soybean/fallow (4,507 kg ha-1) and millet/soybean/millet (4,765 kg ha-1) rotation at no-tillage system, and incorporated fallow /soybean/ incorporated fallow (4,427 kg ha-1) at conventional tillage system allow the highest rice yield; upland rice yield is similar at no-till (3,194 kg ha-1) and till system (2,878 kg ha-1).

Floristic composition of a conservation area in the Federal District of Brazil

Cerradão vegetation shares many species with savanna and forest areas and is one of the most vulnerable phytophysiognomies in the Cerrado (Brazilian savanna) biome. The floristic composition of the Cerradão Biological Reserve was examined between September/2007 and November/2008. A total of 282 species distributed among 194 genera and 75 families were encountered, demonstrating proportions of 0.91 herbaceous species and 0.54 shrub species for each tree species. Fabaceae, Asteraceae, Rubiaceae, Poaceae, Myrtaceae, Malpighiaceae, and Melastomataceae were the most species-rich families. Fully 72.3% of the species of this dystrophic cerradão were shared by cerrado and forest vegetations, while 60.43% were shared by other cerradão sites, although the largest proportion of species (91%) were shared with cerrado sensu stricto. No species was found to be exclusive to this cerradão site, but approximately 95% of all species were native to the Cerrado biome.

Influence of first morning urine volume, fasting blood glucose and glycosylated hemoglobin on first morning urinary albumin concentration

The aim of the present study was to evaluate the effect of first morning urinary volume (collected on three different non-consecutive days), fasting blood glucose (determined on the first and third days of urine collection), and glycosylated hemoglobin (determined on the first and third days of urine collection) on the albumin concentration in first morning urine samples collected on three different days. We found 3.6% asymptomatic bacteriuria in the urine samples; therefore, every urine sample must be tested to exclude infection. One hundred and fifty urine samples were provided by 50 IDDM patients aged 21.9 ± 7 (12-38) years with a disease duration of 6.8 ± 5.8 (0.4-31) years attending the Diabetes Clinic at the State University Hospital of Rio de Janeiro. There were no differences in albumin concentration (6.1 vs 5.8 vs 6.2 µg/ml; P = NS) or urinary volume (222.5 vs 210 vs 200 ml) between the three samples. In addition, there were no differences in fasting blood glucose (181.9 ± 93.6 vs 194.6 ± 104.7 mg%; P = NS) or glycosylated hemoglobin (HbA1)(8.4 ± 1.3 vs 8.8 ± 1.5%; P = NS) between the first and third blood samples. Six patients (group 1) had a mean urinary albumin concentration of more than 20 µg/ml for the three urine samples. This group was compared with the 44 patients (group 2) with a mean urinary albumin concentration for the three urine samples of less than 20 µg/ml. No difference was found between groups 1 and 2 in relation to fasting blood glucose (207.1 ± 71.7 vs 187.6 ± 84.6 mg/dl), HbA1 (8.1 ± 0.9 vs 8.6 ± 1.1%) or urinary volume [202 (48.3-435) vs 246 (77.3-683.3) ml]. Stepwise multiple regression analysis with albumin concentration of first morning urine samples as the dependent variable, and urinary volume, fasting blood glucose and glycosylated hemoglobin as independent variables, showed that only 12% (P = 0.01) of the albumin concentration could be accounted for by the independent effect of morning urine volume on the first day of urine collection. No urine samples showed a change in the cutoff level of 20 µg/ml of albumin concentration as the result of volume. Fasting blood glucose and glycosylated hemoglobin did not influence the urinary albumin concentration. Considerable variability in urinary albumin concentration was found in the three morning urine samples with a mean intraindividual coefficient variation of 56%. In conclusion, in the present study, urinary volume had a minimal, though not constant, effect on first morning urinary albumin concentration. Day-to-day metabolic and clinical control of IDDM patients, except probably for ketoacidosis, should not contraindicate microalbuminuria screening in first morning urine samples

Myocyte necrosis is the basis for fibrosis in renovascular hypertensive rats

The pathogenesis of fibrosis and the functional features of pressure overload myocardial hypertrophy are still controversial. The objectives of the present study were to evaluate the function and morphology of the hypertrophied myocardium in renovascular hypertensive (RHT) rats. Male Wistar rats were sacrificed at week 4 (RHT4) and 8 (RHT8) after unilateral renal ischemia (Goldblatt II hypertension model). Normotensive rats were used as controls. Myocardial function was analyzed in isolated papillary muscle preparations, morphological features were defined by light microscopy, and myocardial hydroxyproline concentration (HOP) was determined by spectrophotometry. Renal artery clipping resulted in elevated systolic arterial pressure (RHT4: 178 ± 19 mmHg and RHT8: 194 ± 24 mmHg, P<0.05 vs control: 123 ± 7 mmHg). Myocardial hypertrophy was observed in both renovascular hypertensive groups. The myocardial HOP concentration was increased in the RHT8 group (control: 2.93 ± 0.38 µg/mg; RHT4: 3.02 ± 0.40 µg/mg; RHT8: 3.44 ± 0.45 µg/mg of dry tissue, P<0.05 vs control and RHT4 groups). The morphological study demonstrated myocyte necrosis, vascular damage and cellular inflammatory response throughout the experimental period. The increased cellularity was more intense in the adventitia of the arterioles. As a consequence of myocyte necrosis, there was an early, local, conjunctive stroma collapse with disarray and thickening of the argyrophilic interstitial fibers, followed by scarring. The functional data showed an increased passive myocardial stiffness in the RHT4 group. We conclude that renovascular hypertension induces myocyte and arteriole necrosis. Reparative fibrosis occurred as a consequence of the inflammatory response to necrosis. The mechanical behavior of the isolated papillary muscle was normal, except for an early increased myocardial passive stiffness

Lack of a relationship between serum ferritin levels and coronary atherosclerosis evaluated by coronary arteriography

Many clinical and epidemiological studies have demonstrated the relationship between serum ferritin and ischemic heart disease. In the present study we evaluated the relationship between coronary heart disease (CHD) and serum ferritin levels in patients submitted to coronary arteriography. We evaluated 307 patients (210 (68.7%) males; median age: 60 years) who were submitted to coronary angiography, measurement of serum ferritin and identification of clinical events of ischemic heart disease. Serum ferritin is reported as quartiles. Ninety-six patients (31.27%) had normal coronary angiography (group 1) and 211 (68.73%) had coronary heart disease (group 2). Of the patients with CHD, 61 (28.9%) had serum ferritin levels higher than 194 ng/ml (4th quartile), as opposed to only 14 (14.58%) of those without CHD (P = 0.0067). In the 2nd quartile, 39 patients (18.48%) had CHD, while 35 patients (36.46%) had normal coronary arteries (P = 0.00064). Multivariate analysis of the data showed that the difference between groups was not statistically significant (P = 0.33). We conclude that there is no independent relationship between coronary heart disease and increased levels of serum ferritin.

Effect of the injection of an extract of Ascaris suum on macrophage activation during the early phase of Mycobacterium bovis BCG infection in C57Bl/6 mice

Injection of an Ascaris suum extract (Asc) affects both the humoral and cellular immune responses to unrelated antigens when it is co-administered with these antigens. In the present study we evaluated the effect of Asc on macrophage activation in the early phase of Mycobacterium bovis BCG (Pasteur strain TMCC 1173) infection in C57Bl/6 mice. C57Bl/6 mice were injected intraperitoneally (ip) with 0.1 mg BCG (BCG group) or BCG plus 1 mg Asc (BCG + Asc group). The peritoneal exudates were obtained at 2, 7 and 14 days after infection. The numbers of IFN-g-secreting cells were assessed by the ELISPOT assay. Nitric oxide (NO) production was measured by the Griess method and by the evaluation of NADPH diaphorase activity in the peritoneal exudates. The administration of Asc extract increased NADPH diaphorase activity (2 days: control = 0, BCG = 7%, BCG + Asc = 13%, and Asc = 4%; 7 days: control = 4, BCG = 13%, BCG + Asc = 21%, and Asc = 4.5%) and TNF-a levels (mean ± SD; 2 days: control = 0, BCG = 169 ± 13, BCG + Asc = 202 ± 37, and Asc = 0; 7 days: control = 0, BCG = 545 ± 15.5, BCG + Asc = 2206 ± 160.6, and Asc = 126 ± 26; 14 days: control = 10 ± 1.45, BCG = 9 ± 1.15, BCG + Asc = 126 ± 18, and Asc = 880 ± 47.67 pg/ml) in the early phase of BCG infection. Low levels of NO production were detected at 2 and 7 days after BCG infection, increasing at 14 days (mean ± SD; 2 days: control = 0, BCG = 3.7 ± 1.59, BCG + Asc = 0.82 ± 0.005, Asc = 0.48 ± 0.33; 7 days: control = 0, BCG = 2.78 ± 1.54, BCG + Asc = 3.07 ± 1.05, Asc = 0; 14 days: control = 0, BCG = 9.05 ± 0.53, BCG + Asc = 9.61 ± 0.81, Asc = 10.5 ± 0.2 (2 x 106) cells/ml). Furthermore, we also observed that Asc co-injection induced a decrease of BCG-colony-forming units (CFU) in the spleens of BCG-infected mice during the first week of infection (mean ± SD; 2 days: BCG = 1.13 ± 0.07 and BCG + Asc = 0.798 ± 0.305; 7 days: BCG = 1.375 ± 0.194 and BCG + Asc = 0.548 ± 0.0226; 14 days: BCG = 0.473 ± 0.184 and BCG + Asc = 0.675 ± 0.065 (x 102) CFU). The present data suggest that Asc induces the enhancement of the immune response in the early phase of BCG infection.
