Anti-spermatogenic activity of malvidin chloride in langur monkeys (Presbytis entellus entellus Dufresne)

Plasma levels of estradiol and progesterone during normal menstrual cycle in langur monkey (Presbytis entellus entellus)

Cadmium induced changes in the liver of langurs (Presbytis entellus-entellus dufresne).

1- Cadmium-induced hepatic disturbances in Langurs have been studied following a single low dose administration of the salt (Cd Cl2 4 mg/kg s.c.). 2-Serum transaminases, choelsterol and liver glycogen levels were elevated. Alkaline phosphatase levels were in normal range. The blood sugar was at a low level. 3- Degranulation, vacuolization and distortion of the liver cells and lobules were consp...

The primary structure of langur (Presbytis entellus) pancreatic ribonuclease: adaptive features in digestive enzymes in mammals.

The primary structure of pancreatic ribonuclease from langur (Presbytis entellus) has been determined. This sequence differs from that of human pancreatic ribonuclease at 14 (11%) of the amino acid positions. Eight of these 14 differences involve changes of charge, with the langur enzyme having five fewer positive charges than the human enzyme. The difference in charge between human and langur ...

Sperm motility inhibitory effect of the benzene chromatographic fraction of the chloroform extract of the seeds of Carica papaya in langur monkey, Presbytis entellus entellus.

AIM To assess the contraceptive efficacy of the benzene chromatographic fraction of the chloroform extract of the seeds of Carica papaya in langur monkeys. METHODS The test substance was given p.o. to five monkeys at 50 mg/kg body weight/day for 360 days. Control animals (n=3) received olive oil as vehicle. Sperm parameters as per World Health Organization standards, sperm functional tests, m...

Establishment of asymptomatic Leishmania donovani infection in Indian langurs (Presbytis entellus) through intradermal route.

Indian langurs, which were previously reported to be highly susceptible, were infected intradermally using variable numbers of promastigotes along with different doses, 1/2 pair, 5 pairs and 10 pairs respectively of salivary gland lysate (SGL). Although, all the monkeys developed mild infection and remained subclinically infected throughout the observation period, which later resolved, none of ...
