Preclinical assessment of analgesic, anti-inflammatory and antipyretic potential of Fragaria ananassa and Actinidia deliciosa fruit extract.

Fragaria ananassa (garden strawberry) and Actinidia deliciosa (kiwi) fruits are widely consumed due to their taste and nutritive value however several studies also supports their medicinal uses. Current study was designed to assess the In-Vivo analgesic, anti-inflammatory and antipyretic activity of ethanol extract of Fragaria ananassa (EEFA), Actinidia deliciosa (EEDA) and their 1:1 combination. Albino Wistar rats were divided into five groups (n=5) for each study comprising of vehicle control, reference standards *(aspirin and paracetamol 100 mg/kg/day), EEFA (800 mg/kg/day), EEAD (800 mg/kg/day) and 1:1 combination of EEFA and EEAD (400 + 400mg/kg/day). The results revealed significant anti-inflammatory potential of EEAD and their combination with 79.35% and 82.03% inhibition in carrageenan induced paw edema whereas 52.54% inhibition was produced by EEFA against control. However most powerful analgesic effect was produced by EEFA with 52.23% at 60 min followed by EEAD (48.38%) and EEFA+ EEAD combination (44.09%). Similarly, EEFA, EEAD and their combination also lowered the rectal temperature in highly significant manner (p< 0.01) against control. These results suggested the possible role of garden strawberry and kiwi in treating the ailments related to pain, inflammation and fever however further studies are required to elucidate the constituents responsible for it and their exact mechanism.

Dose dependent anticonvulsant activity of Morus nigra in strychnine induced seizures model.

Herbal medicines have gained tremendous surge of interest in recent years. M. nigra leaves are a rich source of phenolics which are well-known for their antioxidant property. Morus nigra popularly known as black mulberry is considered to be the most significant species of genus Morus. This study was designed to evaluate its activity on seizure model in different doses. Five groups were made comprising of n=10 animals in each group respectively. Group I was on distilled water, Group II was administered with reference drug diazepam and Group III, IV and V were on 125mg/kg, 250mg/kg and 500mg/kg dose of Morus nigra for 15 days prior to experiment. On day 16th all animals were administered with strychnine after 30 minutes of respective treatments and three parameters were recorded i.e. duration, frequency and onset of seizures. M. nigra treatment showed significant seizure protection as noted by delayed latency of seizures (P<0.05), decrease in frequency and jerk's duration (P<0.05) in comparison to control and reference standard. Most significant (P<0.05) anticonvulsant effects were observed with 500mg/kg dose. Anticonvulsant activity of M. nigra could be due to potentiation of both Gabaergic and glycinergic activities. Antiepileptic potential of extract could also be amplified due to its antioxidant activity. This could serve as a non-pharmacological treatment for seizure management.
