Medicinal plants as hepatoprotective agents in Indian systems of medicine: A review

Author: Anjana Jadon

Liver is a most important organ of the body. It plays an important role to maintaining various physiological processes in the body. It is involved in several vital functions, such as metabolism, secretion and storage. It plays a central role in the detoxification and excretion of many exogenous and endogenous compounds. Hence, any injury or impairment of its function has grave implications for the health of the affected person. Many more drugs or therapies are available for the treatment of hepatic disorders, but still there is a need for the novel drug discovery which can target multiple disease pathways. In the 21st century has a great that paradigm shift towards therapeutic evaluation of herbal products. The use of herbal products has a great role in the treatment of liver diseases and has no side effects. There are a number of hepatoprotective plants have been reported. In this review article, effort has been taken to collect and compile the details of hepatoprotective plants, which will be helpful in the field of Indian system of medicines.

PASSIVE OPTICAL NETWORKS: A FUTURESTIC APPROACH

This paper is to know about the meaning of passive optical network`s and its architecture. It explains the different types of passive optical networks and its uses for the present as well as future of the communication. Passive optical networks provide the huge bandwidth for the data transmission for triple play (video-voice-data) simultaneously. Requirement for the high speed communication networks is the high bandwidth for the data transmission without interruption. Passive optical networks provide this facility very effectively.

Isolation and screening of thermophilic lignolytic bacterial strains for lignin degrading enzymes

In the present investigation, total twenty two thermophilic lignolytic bacterial cultures were isolated from various sources using Nutrient Agar (NA) and Minimal Salt Medium (MSM) medium with Lignin Alkali (1.0 g/L) by incubating at pH 7 and 50°C for 48 hrs. These isolates were characterized by special reference to their ability towards wide temperature, pH resilience and generation of thermophilic enzymes. For the screening and studying lignin degrading potential, these microbes were grown on MSM agar plates with Methylene Blue dye (0.25g/L). After the incubation time of 48 hrs, these plates were observed for clear (halo) zones form around the streaked strain. Only 5 strains were showing such clear (halo) zones which indicates their potential for degrading lignin.  These screened isolates were then used for further experimental work.
