Sarcostemma secamone (L.) Bennet an ethnomedicinal plant was studied for its immunomodulatory activity. Immunomodulatory activity of different doses of ethanol extract of Sarcostemma secamone was evaluated in Swiss albino mice. Mice were treated with two doses (150 and 300mg/kg body weight) for 5 days. Body weight, relative organ weight, delayed type hypersensitivity (DTH) response and Haemaggl...

contamination of aquatic ecosystems with heavy metals has been receiving increased worldwide attention due to their harmful effects on human health and other organisms in the environment. the aim of this study is to elucidate the accumulation and elimination of copper metal on the gill, muscle and skin tissues of black fish, capoeta fusca. sampling was carried out from qantas of birjand area in...

The safety of the stabilized, orally absorbable form of reduced nicotinamide adenine dinucleotide (NADH), known under the brand name ENADA, was investigated over a period of 26 weeks. Eighty healthy rats (40 males and 40 females) were divided into two groups. One tablet ENADA/NADH 5 mg per day was administered orally to one group while identical-looking white tablets not containing NADH (placeb...

Objective criteria are needed for defining, in various animal species, changes occurring at puberty. Particularly required are estimates of the relationship of alterations in the growth of the whole body to the sex organs and the secondary sexual characteristics. A procedure that has been widely employed has been to plot testicular weight as a function of time and to observe inflection points.'...

The objective of this study was to evaluate the effects of parenteral administration of L-arginine (Arg) to well-fed twin-bearing ewes from day (d) 100 of pregnancy to birth on fetal growth, body composition and neonatal behavior. Ewes received an i.v. bolus of either 345 μmol Arg-HCl/kg bodyweight or saline solution (control) 3 times a day. At d 140 of pregnancy, Arg-supplemented and control e...

This experiment was conducted to study the effect of Aflatoxins (AF) on broiler performance, organ weight, plasma characteristics, protein digestibility, and metabolizable energy of the diets. Dietary treatments were: 1) control diet based on corn and soybean meal; 2, 3 and 4) control diet plus 1 mg kg-1 AF, 1 mg kg-1 AF and 0.25% mycosorb, and 0.25% Mycosorb, respectively. The results in the A...
