Effect of the acupoints ST-36 (Zusanli) and SP-6 (Sanyinjiao) on intestinal myoelectric activity of Wistar rats

Despite its ancient use as a therapeutic tool to treat several ailments, acupuncture still faces the challenge of scrutiny by Western science both in terms of its efficacy and in terms of the characterization of its effects and mechanisms of actions underlying these effects. We investigated under well-controlled and carefully characterized conditions the influence of electrical stimulation of acupuncture points ST-36 (Zusanli) and SP-6 (Sanyinjiao) on the myoelectric activity of the small intestine of 38 adult male Wistar rats. Electrical recordings obtained by means of four electrodes chronically implanted in the small intestine were used to assess the effects of acupuncture (electroacupuncture stimulation set at 2 Hz, intermittent stimulation, 1 V, for 30 min). Immobilization of the animals was associated with a consistent decrease (-8 ± 7%) in the myoelectric activity of the small intestine as measured by means of the root mean square. Conversely, acupuncture was able to significantly increase (overshoot) this activity compared to baseline (+44 ± 7%). In contrast, immobilized animals subjected to sham acupuncture had only modest (nonsignificant) increases in myoelectric activity (+9 ± 6%). Using carefully controlled conditions we confirmed previous noncontrolled studies on the ability of acupuncture to alter intestinal motility. The characterization of the topographic and temporal profiles of the effects observed here represents a basis for future dissection of the physiological and pharmacological systems underlying these effects.

The starch from Solanum lycocarpum St. Hill. fruit is not a hypoglycemic agent

We have investigated the hypoglycemic effect induced by the starch obtained from the unripe fruits of Solanum lycocarpum (Solanaceae). Per os administration of the starch (1000 or 2000 mg/kg, twice daily for 7 days, N = 6) did not change glycemia levels of nondiabetic female Swiss mice weighing 25-30 g. In streptozotocin-induced diabetic mice, similar treatment with the starch did not change the elevated glycemia 3 h after the last dose (diabetic treated with saline = 288 ± 17/309 ± 18; starch 1000 mg/kg = 295 ± 33; starch 2000 mg/kg = 258 ± 37; N = 5). In animals fasted for 15 h, per os administration of glucose (600 mg/kg) significantly increased glycemia 1 h later. Previous (-30 min) treatment of the animals with the starch (1000 or 2000 mg/kg; N = 5) did not change the increase of glycemia. Per os administration of the starch (1000 or 2000 mg kg-1 day-1, twice daily for 7 days) did not induce body weight gain or loss. The chemical analysis of the starch indicated the presence of glycoalkaloids, a finding that represents a reason for concern since many of these substances are generally toxic. In interviews with 56 diabetic patients, 29 medicinal plants were reported as useful in their treatment of diabetes and S. lycocarpum was the sixth most frequently mentioned. All patients interviewed reported that they also used insulin or oral hypoglycemic drugs. The results of the present study do not provide evidence for a hypoglycemic effect associated with the polysaccharide fraction of S. lycocarpum in either normal or hyperglycemic mice. These data demonstrate the need for adequate pharmacological investigation of the natural products widely used in folk medicine.

Noninvasive assessment of endothelial function and ST segment changes during exercise testing in coronary artery disease

Endothelial function (EF) plays an important role in the onset and clinical course of atherosclerosis, although its relationship with the presence and extent of coronary artery disease (CAD) has not been well defined. We evaluated EF and the ST segment response to an exercise test in patients with a broad spectrum of CAD defined by coronary angiography. Sixty-two patients submitted to diagnostic catheterization for the evaluation of chest pain or ischemia in a provocative test were divided into three groups according to the presence and severity of atherosclerotic lesions (AL): group 1: normal coronaries (N = 19); group 2: CAD with AL <70% (N = 17); group 3: CAD with AL ≥70% (N = 26). EF was evaluated by the percentage of flow-mediated dilatation (%FMD) in the brachial artery during reactive hyperemia induced by occlusion of the forearm with a pneumatic cuff for 5 min. Fifty-four patients were subjected to an exercise test. Gender and age were not significantly correlated with %FMD. EF was markedly reduced in both groups with CAD (76.5 and 73.1% vs 31.6% in group 1) and a higher frequency of ischemic alterations in the ST segment (70.8%) was observed in the group with obstructive CAD with AL ≥70% during the exercise test. Endothelial dysfunction was observed in patients with CAD, irrespective of the severity of injury. A significantly higher frequency of ischemic alterations in the ST segment was observed in the group with obstructive CAD. EF and exercise ECG differed among the three groups and may provide complementary information for the assessment of CAD.

Caracterização morfológica de frutos, sementes e germinação de Allophylus edulis (St.-Hil.) Radlk. (Sapindaceae)

Os objetivos deste trabalho foram caracterizar morfologicamente as estruturas externa e interna dos frutos e das sementes, além de descrever e ilustrar a morfologia externa da plântula de Allophylus edulis (St.-Hil.) Radlk.. Para a descrição dos frutos foram observados detalhes externos e internos do pericarpo, referentes à textura, consistência, cor, pilosidade, brilho, forma, número de sementes por fruto e deiscência. Para as sementes foram analisadas as seguintes variáveis externas: dimensões, cor, textura, consistência, forma e posição do hilo e da micrópila. Para as características internas, verificou-se presença ou ausência de endosperma, o tipo, a forma, a cor, a posição dos cotilédones, o eixo-hipocótilo-radícula e plúmula. A germinação foi considerada desde a emissão da radícula até a emissão dos protófilos e a plântula foi considerada estabelecida quando os protófilos já estavam totalmente expandidos. Os frutos de Allophylus edulis são do tipo coca, globosa, indeiscentes e monospérmicos. As sementes são ovóides, sem endosperma e o embrião ocupa toda a semente, mais ou menos encurvado e levemente comprimido. A germinação das sementes tem início ao oitavo dia e pode ser encerrada no décimo quinto dia, após a semeadura.

Changes in gene expression during drying and imbibition of desiccation sensitive Magnolia ovata (A. St.-Hil.) spreng. seeds

Seeds of Magnolia ovata were dried to different water contents to assess the viability and transcript abundance of genes related to seed development, cell cycle, cytoskeleton and desiccation tolerance.The expression of development, cell cycle and cytoskeleton relative genes (ABI3, CDC2-like and ACT2) alone could not explain the germination behaviour of M. ovata seeds in relation to drying damage. Irrespective of their initial water content, the seeds performed in the same way during the initial period of germination and the deleterious effects of desiccation only occurred in later stages. Expression of PKABA1, sHSP17.5 and 2-Cys-PRX did not show a relationship with desiccation. However, the expression patterns of PKABA1 and sHSP17.5 suggested the participation of these genes in protective mechanisms during the imbibition of M. ovata seeds.
