Effect of methotrexate and leucovorin on female reproductive tract of albino rats.

Methotrexate (MTX) an antifolate drug and leucovorin its antidote, are used in the treatment of both neoplastic and non-neoplastic diseases in young women. We hypothesize that MTX treatment might comprise a deleterious effect on fast proliferating reproductive cells, an unavoidable and unwanted side effect. MTX given dose dependently to rats for 20 days prevented vaginal cyclicity and caused a reduction in serum progesterone and estradiol.

Studies on methotrexate effects on testicular steroidogenesis in rats.

The effects of single dose, 4 consecutive days, 4 and 8 weekly doses of methotrexate (MTX) treatment (3 mg/kg body weight, intramuscularly) with and without leucovorin (LCN) supplementation (0.3 mg/kg body weight, intramuscularly) on serum testosterone titres, total, free and esterified cholesterol concentrations and steroidogenic enzymes, viz. 3beta- and 17beta-hydroxy steroid dehydrogenase activities were studied in adult albino rats.

Effect of short-term treatment of eugenol on the seminal vesicles of adult albino rats.

The structure and biochemical content of adult albino rat seminal vesicles, were studied, after administration of two different doses of eugenol for 10 days (0.2 and 0.3 mg/kg/day, i.

Effect of short duration caffeine treatment on the jejunum of adult albino rats.

The effect of the short duration (21 days) of caffeine at two different doses (12 mg & 30 mg/kg body weight/day) on the activities of adenosine triphosphatases in jejunum was studied. The activity of Na+, K+ -dependent ATP-ase was reduced significantly in the upper jejunal mucosal and serosal layers of low an high dose groups. Such effect was observed only in the lower jejunal serosal layer while a marked reduction in the activity of Mg2+ATP -ase was seen in mucosal and serosal layers of the jejunum at both doses.

Hepatotoxicity of eugenol.

EUGENOL a widely used pharmaceutical agent proceeds toxicity on inhalation in rats. Two different doses 20 & 30 μg/100g body weight/ day of eugenol were given intramuscularly to male albino rats for 10 days and the liver function was assessed by measuring the specific enzyme activities, and total and differential bilirubin concentration. There was an appreciable increase in total as well as differential bilirubin fractions and a dose dependent increase was noticed in the activities of alkaline phosphatase, transminases, lactate dehyrogenase with a decrease in the activity of glytamyl transferase activity, and suggesting eugenol to have a toxic effect on liver.
