Many customary practices are associated with the health of human in some way. The Assamese Brahmins also practice many customary health practices, which affect the overall health of the human body in many ways. In this study, the customary health practices of Brahmins of Nalbari and Barpeta districts of Assam have been studied. Many practices related to various daily and seasonal activities are prevalent among the Assamese Brahmins. Some such practices are associated with daily activi- ties like cooking, bathing and eating. Customary practices associated with seasonal activities like festivals, Puja and Naam-Kirtan also finds an important place in their lifestyle.

Apart from agriculture as the primary source, these people depend on animal trapping practices as secondary means of livelihood in day-to-day activities. The present work was carried out in East Kameng district of Arunachal Pradesh. People of this area are fond of hunting and fishing using indigenous traps. Almost all the tribes viz; Nyishi, Aka, Miji and Sulungs use the traps for catching preys. These practices are believed to be as old as the human races with close affinity. The simple structures with unique mechanisms these traps are used in certain periods of the year. The technique adopted is unique whose mechanism works on the scientific principle utilizing the restored stress force to trap the living organisms especially birds and mammals.

of the country which attribute to this are the Western Ghats and the Eastern Himalayas. The state of Arunachal Pradesh covers
a major part of the Eastern Himalayan and Indo-Burma hotspots located within India. Arunachal Pradesh is inhabited by 28
major tribes and 110 sub-tribes. One such tribe, the Tangams, with a sparse population, consisting of very few individuals was
found to be settled in the central northern part of the state. They are one of the minor tribes of the state concentrated primarily in
one village with very few instances of migration to other villages. The Tangams resides on the northern Bank of Siang river,
known as Brahmaputra in the lower belt of India. The early Tangams depended solely on local resources including agriculture and
hunting. The study was performed in the Tangam inhabited Kugging village of Upper Siang district of Arunachal Pradesh from
August 2014 to July 2016. In their interactions with the nature, they extracted their needs from nature. However, a detailed
study about their beliefs revealed that in spite of resource extraction, they followed certain customs and taboos which resulted in
sustainable utilization of resources and prevented their indiscriminate destruction. The Tangams worship the nature in the form of
god of animals, plants and soil in various forms and perform various rituals to please them. They believe that that offending them
in any way may lead to unleashing the wrath of these spirits upon the villagers, which may lead to disease and death. Such beliefs
related to animals, plants and other natural resources plays a very important role in resource conservation including biodiversity
conservation. Such sustainable use of resources by the indigenous people is one of the major causes of Eastern Himalayas being one
of the Megabiodiverse regions of the world. In the present times, when many conservation efforts are not successful upto the mark,
the traditional means of conservation practiced by the Tangam people seem to be efficient in conservation of resources and may be
encouraged by the government and local people for retaining the biodiversity.

The rich biodiversity of the region comprises of floras and faunas which also include various forms of palm species. This study was conducted with the help of undergraduate students on the process of preparation of TASSEY from the sugar palm tree Arenga obtusifolia Griff. found in various parts of Arunachal Pradesh. The study area consisted of Kurung Kumey district of Arunachal Pradesh, where parts of Areng tribe of the study area mostly depends on agriculture as their major sustenance with forest products as their secondary source. Tassey, a product obtained from the stem of t people of that area, especially during natural calamity. The paper presents an elaborate description of the whole process of preparation of Tassey with the help of traditional methods and in the form of a white grey powder, which is taken as food in various forms. It is also used as fodder for the domestic animals. Local beverages are also prepared by fermenting it with yeast. Wit this indigenous knowledge is on the verge of extinction. Production of nutritionally rich Tassey can be encouraged by planting more such trees and promoting its marketing. Conservation of such indigenous knowle plant, having ethno medicinal properties is the need of hour.

Customary practices associated with seasonal activities like festivals, Puja and Naam-Kirtan also finds an important place in their lifestyle. Modern day research has elaborated the scientific bases of many such practices followed by Assamese Brahmins. Some practices like fasting can help in keeping the body metabolism in check, leading to a healthy life. Many practices related to children, women and men helps in maintaining the childhood ailments, pregnancy and overall health of the people. The stringent customary practices, which are hard to follow in the present day world, are losing the frequency of use during the present days, leading to extinction of such practices, which evolved over long periods time. Such customary practices can be utilized effectively for preventing present day ailments and also for cure without the use of any additional medicines or medical therapy.

Experiments were carried out in cyclic ovary intact rats during follicular (estrus) and luteal (diestrus) phase and ovariectomized (OVX) female rats. TAM was administered subcutaneously; the uterine horns collected following respective treatments and the effect on the expression of TGF-I in paraffin embedded sections was studied. Immunohistochemical studies were done in both cyclic and OVX female rat uteri to understand the extent of TGF-I expression in various cell types of the uterus, using TGF-I antiserum. Exogenous estradiol-17 (E2) was administered to OVX females to establish the role of E2 as well as TAM in regulating TGF-I expression in the rat uterus. The results showed that TAM decreases TGF-I expression in cyclic ovary intact rats uteri, during both phases under study. Ovariectomy leads to decreased expression of TGF-I in the OVX females, which is restored by administration of exogenous estradiol-17. Administration of E2 and TAM together in OVX rats restores the TGF-I expression, but with lesser intensity than TAM treated OVX females. Both endogenous estrogen of cyclic ovary intact females and exogenous E2 in OVX females are found to be in less effective in regulating the expression of TGF-I in the TAM treated females, evident from a comparatively weaker expression of the growth factor in the TAM treated females' uteri. The study reveals that tamoxifen which is considered as selective estrogen receptor modulator (SERM) alters the pattern of expression of TGF-I in uterine tissue of cyclic females which can not be supplemented either by endogenous estrogen or exogenous estradiol-17 .

The experiments were carried out in both the cyclic and ovariectomised (OVX) female albino rats. Tamoxifen (TAM) has been administered subcutaneously and the uterine horns were collected following the respective treatment in order to study the protein profile by SDS-PAGE in 15% gel. Estradiol-17 (E2) was used to ascertain involvement of certain other factors and TAM in modulating protein profile of the uterus. Tamoxifen induced production of new proteins in the uterus, both in presence and absence of ovary. In ovary intact cyclic female rats, new proteins were synthesized during the follicular and luteal phases along with disappearance of some other proteins in response to TAM. Ovariectomy leads to loss or decreased expression of many proteins in the uterus. Administration of E2, TAM and E2 + TAM induced restoration of many protein found during estrous and diestrous phases. In addition to the original proteins restored, few new proteins were also synthesized in response to the administration of these compounds. The study reveals that tamoxifen alters the protein profile of the ovary intact and ovariectomised female rats which may alter the normal physiology of the reproductive system of female rats.

Pradesh as part of their life and culture. Apart from agriculture as the primary source, these people depend on animal trapping
practices as secondary means of livelihood in day-to-day activities. The present work was carried out in East Kameng district
of Arunachal Pradesh. People of this area are fond of hunting and fishing using indigenous traps. Almost all the tribes viz;
Nyishi, Aka, Miji and Sulungs use the traps for catching preys. These practices are believed to be as old as the human races
with close affinity. The simple structures with unique mechanisms these traps are used in certain periods of the year. The
technique adopted is unique whose mechanism works on the scientific principle utilizing the restored stress force to trap the
living organisms especially birds and mammals. The practice of trapping system is environment friendly, as because these can be
used as and when required without damaging environment and climate. The trapping practice could be reasonably used for
keeping ecological balance when the favourable season or environment arrives for rapid explosion of fauna and flora in the nature.
