Centella asiatica(CeA) is a creeping plant growing in damp places in India and other Asian countries. The leaves of CeA are used for memory enhancement in the Ayurvedic system of medicine, an alternative system of medicine in India. In this study, we have investigated the effect during the rat growth spurt period of CeA fresh leaf extract treatment on the dendritic morphology of hippocampal CA3 neurons, one of the regions of the brain concerned with learning and memory. Neonatal rat pups (7 days old) were fed with 2, 4 or 6 ml kg−1 body weight of fresh leaf extract of CeA for 2, 4 or 6 weeks. After the treatment period the rats were killed, their brains were removed and the hippocampal neurons were impregnated with silver nitrate (Golgi staining). Hippocampal CA3 neurons were traced using a camera lucida, and dendritic branching points (a measure of dendritic arborization) and intersections (a measure of dendritic length) were quantified. These data were compared with data for age-matched control rats. The results showed a significant increase in the dendritic length (intersections) and dendritic branching points along the length of both apical and basal dendrites in rats treated with 4 and 6 ml kg−1 body weight per day of CeA for longer periods of time (i.e. 4 and 6 weeks). We conclude that the constituents/active principles present in CeA fresh leaf extract have a neuronal dendritic growth stimulating property; hence, the extract can be used for enhancing neuronal dendrites in stress and neurodegenerative and memory disorders.

Centella asiatica(CeA) is a creeping herb, growing in moist places in India and other Asian Countries. Ayurvedic system of medicine, an alternate system of medicine in India, uses leaves of CeA for memory enhancement. Here, we have investigated the role of CeA fresh leaf juice treatment during growth spurt period of rats on dendritic morphology of amygdaloid neurons, one of the regions concerned with learning and memory. The present study was conducted on neonatal rat pups. The rat pups (7-days-old) were fed with 2, 4 and 6 ml/kg body of fresh leaf juice of CeA for 2, 4 and 6 weeks. After the treatment period, the rats were killed, brains removed and amygdaloid neurons impregnated with Silver nitrate (Golgi staining). Amygdaloid neurons were traced using camera lucida and dendritic branching points (a measure of dendritic arborization) and intersections (a measure dendritic length) quantified. These data were compared with those of age-matched control rats. The results showed a significant increase in dendritic length (intersections) and dendritic branching points along the length of dendrites of the amygdaloid neurons of rats treated with 4 and 6 ml/kg body weight/day of CeA for longer periods of time (i.e. 4 and 6 weeks). We conclude that constituents/active principles present in CeA fresh leaf juice has neuronal dendritic growth stimulating property; hence it can be used for enhancing neuronal dendrites in stress and other neurodegenerative and memory disorders.

Abstract Clitoria ternatea is a vigorous, herbaceous perennial legume that belongs to the Fabaceae family. All parts of the plant are used in the preparations of Ayurvedic drugs. It is an astringent, an aphrodisiac, a rejuvenator, and a brain tonic. It also has anti-inflammatory, analgesic, and antipyretic properties. Baidyanath Shankapushpi, which contains extracts of herbs such as C. ternatea, Bacopa monnieri, Withania somnifera and Asparagus racemosus, is clinically administered for memory improvement, blood purification and to improve digestion. However, its neuroprotective effect has not been reported so far. In the present study, the neuroprotective effect of C. ternatea root (CTR) extract on hippocampal CA3 neurons was investigated. Three-month-old albino mice were divided into four groups. Group I was the normal control, group II was the saline control, group III was the stress group, and group IV was the stress + CTR-treated group. Group-III mice were stressed in a wire mesh restrainer for 6 hours/day for 6 weeks. Grou-IV mice were also stressed like group III, but received CTR extract orally throughout the stress period. After 6 weeks, their brain was removed, and their hippocampi were dissected and processed for Golgi staining. The hippocampal neurons were traced using a camera lucida focused at 400x magnification. The Sholl concentric circle method was used to quantify the dendrites. The results showed a decrease in the number of dendritic branching points and of dendritic intersections in the stressed group. On the other hand, there was an increase in the number of dendritic branching points and of dendritic intersections of hippocampal CA3 neurons in group IV, which was subjected to restraint stress and was treated with the CTR extract. The results showed that the oral administration of CTR significantly increased the dendritic branching points and the dendritic intersections of hippocampal CA3 neurons.

The study was designed to evaluate the glucose and cholesterol lowering effect of the aqueous extract of Centella asiatica leaf using the alloxan-induced diabetic rats and compared the activity with diabetic control and antidiabetic drug (Glibenclamide). Leaf extract (50 mg/kg) of C. asiatica and Glibenclamide were administered to normal and experimental diabetic rats for the duration of 10 days. In the alloxan-induced diabetic rat model, C. asiatica extract (50 mg/kg) significantly (p < 0.05) lowered the fasting blood glucose level as well as the total cholesterol level. Serum insulin levels were not stimulated in the animals treated with the extract. In addition, changes in body weight, serum lipid profiles and liver glycogen levels assessed in the extract treated diabetic rats were compared with diabetic control and normal animals. Significant results (p < 0.05) were observed in the estimated parameters. Surprisingly, body weight was increased significantly (p < 0.05) in the C. asiatica treated diabetic group. Phytochemical screening showed the presence of alkaloids, flavonoids, glycosides, steroids and tannins in significant amountsJahangirnagar University J. Biol. Sci. 4(1): 51-59, 2015 (June)

The objective of this study was to determine the effect of centella leaf extract administration on decreased of the molecule cAMP responsive element modulator (CREM) expression in the testicular seminiferous tubules of male rats (Rattus norvegicus). Eight rats, aged 3.5 months with 150-250 grams of body weight (BW) were used in this study. All rats were divided randomly into four groups as if K0 as a control group whereas K1, K2, and K3 were given the centella leaf extract with doses 125, 250, and 500 mg / kg body weight respectivelly that given once daily for 30 days. At the end of the treatment, rats were sacrificed and their testes were collected and subsequently fixed in buffered neutral formalin (BNF) 10% as fixative solution for histological preparation. The CREMs expressions were detected using immunohistochemical methods. The results showed that the number of CREM expression in the seminiferous tubules significantly differ (P <0.05) between K0 and the treatment group (K1, K2, and K3). Conclusion, the administration of centella leaf extract with of the dose 125, 250, and 500 mg/kg BW can decreased CREM expression spermatids of testicular seminiferous tubules in male rat.
