Hypoglycemic and antidiabetic profile of the aqueous root extracts of Leptadenia hastata in albino rats.

This study was designed to evaluate the antidiabetic profile and the hypoglycaemic activity of aqueous root extracts of L. hastata in normal and alloxan-induced diabetic rats model. Eighty five albino rats were used for this study out of this thirty five were used subjected to experimental diabetes by the use of alloxan at a dose of 160 mg kg(-1) body weight. Seven experimental groups of five rats per group (A-G) were used for this study. A standard antidiabetic drug (insulin) group (B) and normal saline group (G) serves as positive control. The blood glucose lowering activity of the extract, insulin and normal saline groups were monitored at 0, 1, 3, 6, 12 and 18 hpost extract administration. On the other hand the remaining fifty albino rats were used to determine the acute toxicity and the hypoglycemic activity of the extract. The blood glucose levels of the rats were monitored at 0, 7, 14, 21 and 28 days post extract administration. Oral administration of aqueous root extract at 600 and 800 mg kg(-1) b.wt have significantly (p < 0.05) decreased the blood glucose in diabetic albino rats. On the other hand the hypoglycemic activity of the aqueous root extract on normal rats at dose of 1000 mg kg(-1) b.wt have significantly (p < 0.05) decreases blood glucose level in normal albino rats. The results of the current study have demonstrated the antidiabetic and hypoglycaemic effects of L. hastata aqueous root extracts and underscore its potentials in the management of diabetes mellitus especially following prolonged use in days.

Effect of prolonged oral administration of aqueous ficus sycomorus stem-bark extract on testicular size of growing albino rat / Efecto de la administración oral prolongada de extracto acuoso de la corteza de ficus sycomorus en el tamaño testicular de rata albina en crecimiento

Decoction of Ficus sycomorus stem bark is used to treat infertility involving low sperm counts, but the reproductive risk associated with its use is uncertain. The aqueous stem-bark extract was orally administered at 200-600 mg/kg for 30 days to post-pubertal growing albino rats. Within the period, the live body weights, scrotal diameters and testicular size parameters were estimated. The mean live body weight, scrotal diameter of the control and treated rats significantly (p<0.05) increased as the animals grew, but the treatment did not significantly (p>0.05) affect the parameters. There were no significant (p>0.05) variations in mean testicular size parameters in treated and control rats, and no dose-dependent nor time-dependent effects occurred. Sections of the testes of the treated animals showed active spermatogenesis in the seminiferous tubules with no apparent histological lesions. It is concluded that the use of the crude extract of the Ficus sycomorus within our dose range portends minimal male reproductive risk and underscores the need to study its pro-spermatic effect.

La decocción de la corteza del tallo de Ficus sycomorus se usa para tratar la infertilidad relacionada al bajo conteo de espermatozoides, pero es incierto el riesgo reproductivo asociado con su uso. El extracto acuoso de la corteza se administró, en ratas albinas, por vía oral, en una dosis de 200-600 mg/kg, durante 30 días post-crecimiento puberal. Durante el período, fueron controlados los siguientes parámetros: peso corporal in vivo, diámetro escrotal y tamaño testicular. El promedio de peso corporal in vivo y diámetro escrotal de las ratas control y tratadas, tuvieron un incremento significativo (p<0,05) en los animales, pero el tratamiento no afectó significativamente (p> 0,05) esos parámetros. No hubo variaciones significativas (p> 0,05) en la media de los parámetros tamaño testicular en las ratas tratadas y control, ni tampoco se produjeron efectos dependientes de la dosis, ni en función del tiempo. Las secciones de los testículos de los animales tratados mostraron una espermatogénesis activa a nivel de los túbulos seminíferos, sin lesiones histológicas aparentes. Se concluye, que el uso del extracto crudo de Ficus sycomorus, dentro de una dosis de 200-600 mg/kg, presenta mínimo riesgo en la reproducción masculina, sin embargo, se hace necesario estudiar su efecto pro-espermático.

Phytochemical screening and effect of aqueous extract of Ficus sycomorus L. (Moraceae) stem bark on muscular activity in laboratory animals.

The stembark of Ficus sycomorus was collected, dried and extracted to screen for some chemical constituents and study its effect on muscle contraction. The duodena and recti abdominis of 10 guinea pigs weighing between 330 and 34 g and 10 frogs weighing between 180 and 201 g, respectively were isolated and used for this study. The extract was tested to see its effect on acetylcholine-induced contraction on kymograph. The extract reduced the acetylcholine contractile responses of guinea pigs duodena and recti abdominis muscles of frogs significantly, thus showing inhibitory effect on muscle contraction. The extract showed the presence of gallic tannins, saponins, reducing sugars, alkaloids and flavone aglycones. It was concluded that the extract has inhibitory effect on both smooth and skeletal muscles contractions and contains important constituents for pharmacological activities.

The duodena and recti abdominis of 10 guinea pigs weighing between 330 and 345 g and 10 frogs weighing between 180 and 201 g, respectively, were isolated and used for this study. The extract was tested to see its effect on acetylcholine (ACH) induced contraction on kymograph.

Effect of pregnancy on some biochemical parameters in Sahel goats in semi-arid zones.

The effects of pregnancy on some biochemical parameters were studied using 20 sexually mature, cycling goats with weight range 20-25 kg. They were randomly separated into two groups of 10 animals each. In one group, oestrus was detected while going round with a buck in the morning and evening; a single buck on detection of oestrus mated the does and the does were tagged as pregnant after confirmation of non-return of oestrus. The other group was kept cycling and tagged as non-pregnant. The mean serum glucose concentration in pregnant does was 63.35 +/- 7.70 mg/dl, significantly lower than 71.59 +/- 1.14 mg/dl for non-pregnant does (p < 0.05); the mean serum cholesterol concentrations were 79.48 +/- 14.93 for pregnant and 67.29 +/- 1.10 for non-pregnant does, with significant difference (p < 0.05). Protein (g/dl), urea (mg/dl), creatinine (mg/dl) and free fatty acid (microequiv/L) remained unchanged between the two groups (p > 0.05), as did the liver enzymes (ALT, AST). Therefore this study showed that low serum glucose and high cholesterol levels are features of mid to late pregnancy in Sahel goats.
