Pigeonpea is one of the important pulse crop Madhya Pradesh, a State India. The plant gets infected by pathogen Fusarium udum causing wilt disease, which major constraints in production and productivity pigeonpea. present study aimed to carry out vitro condition assess possible use biocontrol consortia field conditions. Six Trichoderma viz., T1- T. viride + harzianum (JC-I), T2- virens (JC-2), ...

t4 and t3, two major hormones of thyroid gland, are responsible for regulation of “basal metabolism” in the body. thyroid function is regulated primarily by variation in the pituitary tsh. in this study, about four hundred individuals were considered from four iranian populations. they were selected randomly in their cities; shiraz, mashhad, rasht, and ilam. essential family information was ask...

To study the protective effects of maternal thyroxine (T4) and 3,5,3'-triiodothyronine (T3) in congenital hypothyroidism, we gave pregnant rats methimazole (MMI), an antithyroid drug that crosses the placenta, and infused them with three different doses of T4 or T3. The concentrations of both T4 and T3 were determined in maternal and fetal plasma and tissues (obtained near term) by specific RIA...

In order to determine the frequency of thyroxine (T4) toxicosis and study the possibility of usefulness for differentiation between thyrotoxic Graves' disease and destructioninduced thyrotoxicosis, the serum concentrations of T4, triiodothyronine(T3), reverse T3 (rT3), and T4-binding globulin (TBG) and the values of T3-uptake and radioactive iodine uptake (RAIU) were measured, and free, T4 inde...

in vitro studies with trichoderma spp., soil-borne fungal antagonists, demonstrated that a number of isolates produced volatile and non-volatile metabolites capable of inhibiting the growth and sporulation of several soil-borne plant pathogenic fungi. microscopic observations showed that t. harzianm and t. viride, isolated from soil samples from ahwaz and karaj, adversely affected the mycelial ...

In an attempt to define the requirement of T8, T4, and T3 surface molecules in functional interactions occurring between human cytolytic T lymphocytes (CTL) and specific target cells, we have analyzed a large number of CTL clones derived from primary mixed lymphocyte culture (MLC) T cell populations for their susceptibility to inhibition by monoclonal antibodies (mAb) directed against these sur...

The present studies indicate that both the heterogeneity and functional programs of human T lymphocytes can be distinguished. Within the T4 subset, which is responsible for inducer/helper functions in T-T, T-B and T-macrophage interactions, discrete subpopulations are present; T4 cells bearing the 2H4 molecule (T4+2H4+) induce T8+ suppressor effector cells, and T4 cells bearing the 4B4 molecule...

Fusarium head blight (FHB) is an important disease of wheat and causes significant economic and yield losses. The principal pathogen associated with FHB in Manitoba is Gibberella zeae (Schwein.) Petch (anamorph = Fusarium graminearum Schwabe). Trichoderma harzianum Rifai is a well-known biocontrol agent of many plant pathogens. The extracts from 11 T. harzianum isolates and cellfree filtrates w...

background and objectives: different trichoderma species play role as suitable alternative for chemical fertilizers and successful biological tool in stable agriculture. these microorganisms show rivalry in food and place sources. they establish in the rhizosphere of most agricultural and non-agricultural plants via producing spores. they also could induce resistance in plants. these properties...
