The alcoholic extract of the roots of Polygonum hydropiper Linn. was fractionated by column adsorption chromatography. The various fractions obtained were tested for antifertility activity in female albino rats. Petroleum ether, petroleum ether +benzene (1:1 v/v) and benzene +chloroform (1:1 v/v) fractions prevented pregnancy in 8/10, 6/10 and 6/10 albino rats, respectively, while the first two...

the purpose of this study was to evaluate the effect of dietary zinc levels during gestation on physical development of offspring. the statistical population consisted of adult male and female rats (albino-wistar) which were obtained from pasteur institute, iran. after mating, 9 pregnant female rats were divided into 3 groups: 1) zinc deficient group (0.05

In a previous study (1) during the investigation of the mutually reinforced instrumental sexual rqponses in rats a positive correlation has been found between the male and female response latencies. The purpose of the present work was to investigate whether this correlation is related to the mating behavior. Mutually reinforced instrumental responses, rewarded by contact with an animal of the o...

The anti-fertility activity of prostaglandin synthesis inhibitors namely the non-steroidal anti-inflammatory drugs: acetyl salicylic acid, indomethacin and oxyphenbutazone were investigated in male and female albino rats and female albino rabbits. Oxyphenbutazone and indomethacin affected the reproductive process in male rats. Indomethacin 3 mg/kg. and acetyl salicylic acid 300 mg/kg produced s...

Paraphenylenediamine (PPD) is a chemical product used in hair dye preparations and temporary tattoos to fasten the dyeing process intensify its results. PPD can evoke local and/or systemic toxic effects either when utilized topically, inhaled or ingested. The aim of this study was evaluate on liver adult female albino rats. Thirty-two rats were divided into 3 groups. Group I (control group) 16 ...

Petroleum ether extract of seeds of Cassia fistula was screened for the antifertility activity in proven fertile female albino rats at the doses 100, 200 and 500mg/kg b.wt./day. Oral administration of the extract to mated female rats on days 1-5 of pregnancy resulted in a decline in the fertility index, numbers of uterine implants and live fetuses in a dose dependent manner as was confirmed by ...

Acetone extract of Stem of Ocimum gratissimum was screened for the antifertility activity in proven fertile female albino rats at the doses 100, 200 and 500 mg/kg b.wt./day. Oral administration of the extract to mated female rats on days 1-5 of pregnancy resulted in a decline in the fertility index, numbers of uterine implants and live fetuses in a dose dependent manner as was confirmed by lapa...

PURPOSE Biological sex and age are considered as two important factors that may influence the function and structure of the retina, an effect that might be governed by sexual hormones such as estrogen. The purpose of this study was to delineate the influence that biological sex and age exert on the retinal function and structure of rodents and also clarify the effect that the estrus cycle might...

the purpose of this research was to determine the effect of two kinds of diet (zinc deficiency and iron deficiency) on some anthropometrical indexes (body weight and crown-rump length), brain growth and motor function in young rats. adult male and female albino wistar rats were obtained from the breeding colony of pasteur institute, iran. the female albino rats were mated with normal male rats....
