    INTRODUCTION: Nature is the delightful example for the phenomena of symbiosis. Natural products are origin from plants, animals, metals and minerals serving as the basis for the treatment of human disease. Medicinal plants based on tradition system of medicine have been playing an incredible role in providing diagnosis and treatment of human beings especially in developing countries. Utilization of herbal drug has also increased in developed countries. Herbal drug is the oldest form of health care known to mankind. Herbs had been used by all the cultures throughout the history. In modern civilization herbal drug is an integral part of the development. Primitive man observed and appreciated the great diversity of plants available to him. The most use of medicinal plant has been developed through observation of wild animal by trials and errors. As time moved on, each tribe added the medicinal power of herbs in their area based on their knowledge. They collected the information on herbs based on the method and well-defined it in herbal pharmacopoeia. Indeed, well into the 20th century most of the pharmacopoeia of scientific medicine was derived from the herbal lore of native place. Much of the drug commonly use now a day is of herbal origin. Most civilized country USA dispensed about 25% of prescription which contains at least one active ingredient derived from plant materials. Some are made from plant extract others are synthesized to mimic the natural plant compounds. From last five thousand years human being has relied on natural product as the primary source of medicines. However, the last two centuries have brought an explosion to understand how the natural products are produced and how they react with other organisms. The World Health Organization (WHO) estimates that 80% of the world health populations presently use herbal medicines for some aspect of primary health care. SCOPE OF WORK:Autism is a neuro-developmental disorder that manifests early in childhood and it is the prevalence in world wide. . The average prevalence of ASD in Asia, Europe and North America was close to 1%. Management of Autism spectrum disorder is a global problem, successful treatment is very important for controlling the raising alarm of the disease. Till date there is no effective drug available to treat ASD. No herbal drug is proved to manage the severity of symptoms of Autism spectrum disorder. The objective of the present study is, to treat this disorder through nature in the form of herbal medicines or drugs with very minimal adverse effect. ASD among1994-99 born children who turned up adults now were reported with high prevalence. Hence the study was focused on autistic symptoms of adolescent age. The present study is designed to evaluate the effect of hydro-alcoholic root extract of Withania somnifera object-directed behavior, social behavior, cognition development and neuro-inflammation against propionic acid induced Autism Spectrum Disorder (ASD) in mice. So that it may serve clinically for the management of ASD.SUMMARY:The preliminary phytochemical studies on HAREWS discovered the presence of various phytoconstituents such as alkaloid, carbohydrates, glycosides, steroid, proteins, flavonoids and saponin. The habituation behavior of HAREWS on PPA induced ASD assessed by objective directed behavior; novel mice vs. novel object directed behavior, nociception threshold, elevated plus maze task and cognition development assessed by Morris water maze task. The habituation behavior on open field revealed that HAREWS significantly reversed stereotypic and staggering movement. Memory retention was assessed on Morris water maze and HAREWS found greatly improved/enhanced the spatial memory. On HAREWS treatment the pain threshold was maintained as like normal subjects. Both propionic acid and HAREWS has found not to possess significant anxiety activity. The biochemical changes that are responsible for stereotypic activity, cognition impairment, and neuro inflammation were assessed by estimating serotonin, TNF-α, Interleukin-6 respectively. HAREWS provided favorable effect on these above biochemicals. The antioxidants defense in the brain tissues were estimated in terms of SOD, CAT, LPO, GPx, GRD and HAREWS increased the antioxidant levels at respective dose leading to reduce oxidative stress. This clearly indicates the potential of the extract to delay the generation of free radicals that cause neuronal damage. The histopathology of ASD mice showed increased in neuron number and reduced size as seen in ASD patients. Whereas the control and HAREWS treated mice showed normal level of neuronal size and counts.CONCLUSION:The present study demonstrated that ICV-infusion of propionic acid induced autism spectrum disorder in mice. Hydro-alcoholic root extract of Withania somnifera helps in improving object directed behavior, social behavior and cognitive skill. And also improve the neuro-inflammation. It also showed the anti-oxidant property which act as a neruo-protective. Further studies are expected on the isolated components of the extract in order to understand the exact mechanism of its action and also studies at cellular level changes by more sophisticated methods for investigation

    A study on diversity, seasonal occurrence, distribution percentage of microalgal taxa and physico-chemical parameters of five community ponds, located in Chinsurah town, Hooghly district of West Bengal, has been carried out. Correlation between occurrence of microalgal genera and some parameters of environment, physico-chemical nature of natural water bodies were explored by Canonical Correspondence Analysis (CCA). Diversity indices have been calculated using PAST software program. A total of 23 microalgal taxa belonging to four algal classes were recorded and the study indicated that the microalgal diversity vary with variation in physico-chemical parameters of water and light intensity. Out of these genera, occurrence of Chodatella sp. in late summer and Tetrallantos sp. and Synechocystis sp. in winter season were specific. In CCA, multiple variables (dissolved oxygen, water temperature, electrical conductivity, pH, light intensity and inorganic phosphorous) played a significant role in occurrence of microalgal taxa. Observation concluded that the Chlorophycean members were dominant throughout the study period and the Shannon–Wiener diversity index was highest for a site with large number of Chlorophycean member. This study will help in future to assess water quality

    Background- High blood pressure is a very common disease in most countries. This can also cause the worsening of other cardiovascular disorders. The total number of people who are suffering from hypertension has elevated in the past thirty years. It impacts the quality of life and it can be caused due to many factors like the lifestyle of the patient (inactivity), stress, obesity, stress, alcohol consumption, unhealthy food habits, age, and other underlying diseases. It is estimated that the cases of hypertension will rise up to 23.25 % by the year 2025 in India. Its occurrence in urban areas is more compared to the rural areas. In order to treat hypertension alternative medication can be used. Method- To carry out this review we searched out the articles from various databases which includes PubMed, web of science and google scholar. All the papers that discussed about hypertension and its herbal remedies were screened. Conclusion- Thus, the current review aimed to highlight various herbal drugs used for the treatment of hypertension. Many patients prefer herbal remedies over modern drugs. There are many herbal drugs available, which can be used for the successful treatment of high blood pressure like hibiscus, tulsi, garlic, Ashoka and etc

    Explicit impacts of harvesting on a fractional-order delayed predator–prey model

    We propose a fractional-order prey-predator model with delay and harvesting. Comparatively, only a few analyses are made to explore the impact of harvesting on population fluctuation due to time delay and fractional order. Thus, our focus is whether harvesting effort can stabilize or destabilize the system by varying the fractional order or keeping it fixed. We have observed that fractional order influences the delayed system and the number of stability switching differently in the case of either predator or prey harvesting. Both fractional order and predator harvesting have a destabilizing effect, whereas prey harvesting has a stabilizing effect on the system. In addition, we observed stability switching induced by predator harvesting while keeping the delay fixed. Moreover, in the case of predator harvesting, when the carrying capacity of prey exceeds a certain threshold, the number of switching regions increases significantly. For yield maximization, we observe that maximum sustainable yield (MSY) exists for predator harvesting only; however, yield at MSY produces stable stock only when the time delay is minimal
