Pigment Synthesis

A General description of the development of mouse chimaerae and an account of the techniques for their production were given in previous reports (Tarkowski, 1961, 1963). The chimaeric character of the embryos and young obtained was tentatively claimed in the first of these publications because (1) the actual union of two eggs into one blastocyst was seen in culture in vitro, (2) of the occurrence of intersexes, (3) pigment synthesis of the types of the dark component occurred in the majority of individuals developed from pairs of eggs differing genetically in factors for pigmentation. The last criterion was met only by macroscopic search for pigment in the eyes. The present report gives a more detailed description of the distribution of pigment forming cells in these animals, based on histological analysis. Some remarks on the validity and applicability of such a criterion for estimating the degree of chimaerism were made at the 13th Annual Meeting of the Tissue Culture Association (Tarkowski 1963).

Colocasia esculenta is commonly known as Taro, it is referred to as cocoyam in Nigeria. They are cherished for their rich taste, nutritional and medicinal properties. Every 100 g of taro corms possess 112 Kcal, 26.46 g carbohydrate, 1.50 g protein, 0.20 g total fat and 4.1g fiber (USDA National Nutrient Data Base). Besides its nutritional value, taro is used as a medical plant and provides bioactive compounds used as an anti-cancer drugs. Traditionally, cocoyams are vegetative propagated from tuber fragments, a practice that encourages pathogen distribution. Colocasia esculenta is a widely distributed food crop in the humid tropics and subtropics. Despite of its wide distribution, Taro plants are commonly infected with DsMV and other pathogens. This virus induces conspicuous mosaic, malformation, dwarfing or feathering on leaves in taro. As the results of infection, it reduces the quality and yield of taro production greatly. This virus is thus considered as a major limiting factor in the production of taro. Here plays the importance of  tissue culture plays a major role in producing the disease resistant plants round the year with high quality. For rapid multiplication and production of quality planting materials, tissue culture technology offers promising alternative compared to the traditional production methods.

Ovarian Tumours

ABSTRACT An in vitro study has been made of experimentally produced rat ovarian tumours of different age, paying particular attention to tumour reaction to crystallized steroids. Tumours of two histological structures were found: granulosa cell – luteoma tumours and arrhenoblastoma tumours. Both types grew in vitro and pictures of their cell appearance are given. The former type gave the best growth, and the endocrine studies were restricted to this type. The steroids tested (androsterone, oestrone, progesterone) all had an arresting effect in certain cases. This effect is not an unspecific, toxic one. The different tumours react to different extents, some being completely unaffected.

Plant Latex

Latex, a milky fluid found in several plants, is widely used for many purposes, and its proteins have been investigated by researchers. Many studies have shown that latex produced by some plant species is a natural source of biologically active compounds, and many of the hydrolytic enzymes are related to health benefits. Research on the characterization and industrial and pharmaceutical utility of latex has progressed in recent years. Latex proteins are associated with plants’ defense mechanisms, against attacks by fungi. In this respect, there are several biotechnological applications of antifungal proteins. Some findings reveal that antifungal proteins inhibit fungi by interrupting the synthesis of fungal cell walls or rupturing the membrane. Moreover, both phytopathogenic and clinical fungal strains are susceptible to latex proteins. The present review describes some important features of proteins isolated from plant latex which presented in vitro antifungal activities: protein classification, function, molecular weight, isoelectric point, as well as the fungal species that are inhibited by them. We also discuss their mechanisms of action.
