RESUMO
BACKGROUND: Triphaladi kvatha is well known herbal Ayurvedic formulation used in Prameha (~type 2 diabetes mellitus). In the present study, kvatha was converted into granules and assessed for its hypoglycemic and anti-hyperglycemic effects in albino mice. MATERIALS AND METHODS: Triphaladi granules (650 mg/kg, p.o.) were administered in normal albino mice for assessment of hypoglycemic activity. Anti-hyperglycemic activity of Triphaladi granules was assessed in glucose (5 g/kg, p.o.) solution overloaded mice. The blood sugar level (BSL) was measured with the help of one touch easy glucometer. RESULTS: Triphaladi granules produced significant decrease in blood glucose level after one hour in comparison to initial values while decreasing BSL by 27.92% in comparison to control group in normal albino mice. In hyperglycemic study, Triphaladi granules produced significant decrease the BSL after 2 hr. of administration compared to control group. CONCLUSION: Triphaladi granules have significant hypoglycemic and anti-hyperglycemic activity in mice with minimal effect on BSL below normal range. The studies suggest the potential role of Triphaladi granules as an alternative adjuvant therapy in diabetic individuals for the control of the blood glucose level.
RESUMO
Present study was undertaken to evaluate analgesic activity of root of Nelsonia canescens (Lam.) Spreng, a folklore medicinal plant used as the one of the source plant of Rasna. Study was carried out at two dose levels (270 mg/kg and 540 mg/kg) in albino rats. Analgesic activity was evaluated in formalin induced paw licking, and tail flick methods whereas indomethacin and pentazocine were used as standard analgesic drugs, respectively. At both the dose levels, test drug non-significantly decreased paw licking response at both time intervals. In tail flick model, the administration of the test drug increased pain threshold response in a dose dependent manner. In therapeutically equivalent dose level, analgesic activity was observed only after 180 min while in TED ×2 treated group analgesia was observed at 30 min and lasted even up to 240 min. The results suggested that N.canescens root possess moderate analgesic activity.
RESUMO
Linaria ramosissima (Wall.) Janch., Scrophulariaceae, a folklore plant, has been claimed for its diuretic activities by traditional practitioners. The present study was undertaken to investigate the diuretic activity of L. ramosissima leaves in albino rats. Suspension of leaf powder in 2% gum acacia was administered to experimental rats orally at doses of 450 mg/kg. The diuretic effect was evaluated by measuring the urine volume, pH of urine, and urinary electrolyte excretion. Administration of the test drug increased the urine volume in a non-significant manner, while it enhanced the urinary excretion of sodium, chloride, and potassium significantly, in comparison to the control group. From the present study it can be concluded that the leaves of L. ramosissima have a significant diuretic activity.
RESUMO
Ashwagandharishta, an Ayurvedic classical formulation, is the remedy for Apasmara (epilepsy), Murchha (syncope), Unmada (psychosis), etc. Recent studies in animal models have shown that n-3 PUFAs can raise the threshold of epileptic seizures. The indigenous medicinal plant, called Atasi (Linum usitatissimum Linn.) in Ayurveda, or flax seed, is the best plant source of omega-3 fatty acids. The present study is designed to investigate whether Ashwagandharishta and Atasi taila (flax seed oil) protect against maximal electroshock (MES) seizures in albino rats. Further, a possible protective role of flax seed oil as an adjuvant to Ashwagandharishta in its anticonvulsant activity has also been evaluated in the study. MES seizures were induced for rats and seizure severity was assessed by the duration of hind limb extensor phase. Phenytoin was used as the standard antiepileptic drug for comparison. Both flax seed oil and Ashwagandharishta significantly decreased convulsion phase. Pre-treatment with flax seed oil exhibited significant anticonvulsant activity by decreasing the duration of tonic extensor phase. Contrary to the expectations, pre-treatment with flax seed oil as an adjuvant to Ashwagandharishta failed to decrease the tonic extensor phase; however, it significantly decreased the flexion phase (P < 0.001) and duration of the convulsions (P < 0.05). Both the drugs exhibited an excellent anti-post-ictal depression effect and complete protection against mortality.
