Macrophage activity and histopathology of the lymphohematopoietic organs in male Wistar rats orally exposed to single or mixed pesticides

The noxious effects of low or effective dose exposure to single or mixed pesticides on macrophage activity and the lymphohematopoietic organs were investigated. Male Wistar rats were orally exposed to dichlorvos, dicofol, endosulfan, dieldrin and permethrin, either as single or combined mixtures during a 28-day study containing eight groups: one group received a semipurified diet (non-treated); two groups received a semipurified diet containing low dose mixture (dieldrin 0.025 mg/kg, endosulfan, 0.6 mg/kg, dicofol 0.22 mg/kg, dichlorvos 0.23 mg/kg, permethrin 5 mg/kg) or an effective dose mixture (dichlorvos 2.3 mg/kg, dicofol 2.5 mg/kg, endosulfan 2.9 mg/kg, dieldrin 0.05 mg/kg and permethrin 25.0 mg/kg), respectively; the other five groups received a semipurified diet containing each single pesticide in effective doses. At sacrifice, the thymus, spleen, mesenteric lymph nodes, Payer's patches and bone marrow were removed for histological analysis. Peritoneal macrophages were obtained to determine the phagocytosis and spreading indexes and tumoral necrosis factor alpha (TNF-α), nitric oxide (NO) and H2O2 production. Exposure to pesticide mixtures did not alter the percentage of macrophage phagocytosis and spreading, TNF-α production or the NO and H2O2 release when compared to the non-treated group. Neither was there any apparent evidence that a pesticide mixture at low or effective doses altered the histological structure of the lymphohematopoietic organs. The findings indicate that short-term treatment with pesticide mixtures did not induce an apparent immunotoxic effect in male Wistar rats. © 2013 Copyright Taylor and Francis Group, LLC.

Summary of resolutions recently adopted by CDCC and resolutions of ECLAC and other organs of the United Nations which might be of special interest to member countries of ECLAC/CDCC

This paper brings to the attention of member countries of the Caribbean Development and Cooperation Committee (CDCC) resolutions adopted by past sessions of the Committee, since 2000, and the process of their implementation. Resolutions 55 to 66 for the period 2000- 2006 have been extracted from the reports of the eighteenth to twenty first sessions of the CDCC Also included for the information of member countries are selected resolutions recently adopted by the Economic Commission for Latin America and the Caribbean (ECLAC) and other organs of the United Nations. These resolutions greatly influence the preparation of the programme of work and are expected guide the day-to-day functioning of the secretariat. It is a great source of information for delegations, given the perceived special relevance of the resolutions to the membership of the CDCC. The resolutions listed in this document are pertinent to all subprogrammes of ECLAC and indeed the CDCC subprogramme 12 of ECLAC. However, the content of these resolutions either marked no real advance on the outcomes of the corresponding conferences that were held within recent times or were cast in a globally relevant context that did not address specific concerns of Caribbean countries to any significant extent.

Allometry of Organs and the Gastrintestinal Tract from Water Buffaloes (Bubalus bubalis) Finished in Feedlot

The objective of present study was to evaluate the relative growth of organs and viscera from water buffaloes. Fifteen Mediterranean intact males, averaging, 356.7 kg initial live weight and twenty four months of age, were used. The animals were ramdomly assigned into three groups (categories). One group was ramdomly assigned to immediate slaughter (AR), the rest two groups were full-fed a ration containing 50% concentrate, dry matter basis until reaching the slaughter weights of 450 and 500kg, respectively. At slaughter the empty body weight was determined and the weights of head, feet, leather, lungs, heart, liver, spleen, rumen-reticulum, omasum, abomasum, small intestine, large intestine were recorded. Regression equations of log weight of organs and viscera as a function of log empty-body-weight (EBW), were fitted. All body components studied, with exception of liver and spleen, developed slower than in relation to EBW.

Comparison of growth curve parameters of organs and body components in meat- (Coturnix coturnix coturnix) and laying-type (Coturnix coturnix japonica) quail show interactions between gender and genotype

The objective of this study was to estimate growth parameters of carcass components (wing, thighs and drumsticks, back and breast) and organs (heart, liver, gizzard and gut) in males and females of one meat-type quail strain (Coturnix coturnix coturnix) and two laying strains (Coturnix coturnix japonica) designated either yellow or red.A total of 1350 quail from 1 to 42d old were distributed in a completely randomised design, with 5 replicates of each strain. The carcass component weights and body organs were analysed weekly and evaluated using the Gompertz function; growth rates were evaluated through derivative equations.The meat-type strain presented the highest growth rates in carcass components and organs. Across strains, females showed the highest weight of internal organs at maturity compared to males.Females had greater growth potential in breast, wings and back than males for both yellow and red laying quail.

Some effects of cimetidine on the reproductive organs of rats

1. The development of genital organs of rats chronically treated with cimetidine showed that the drug may present anti-androgenic activity. 2. This treatment did not alter the sensitivity of vas deferens to noradrenaline, but increased their sensitivity to BaCl2. 3. In the male reproductive system, cimetidine must have peripheral actions apart from the central ones observed after chronic treatment.
