The botanical origins of Cynanchum species (Cynanchum spp.) on the Taiwan market have been established by histological studies in the present paper. The results showed that the Chinese crude drug Pai-wei on the Taiwan market was derived from the dried roots of Cynanchum atratum Bunge; that of Pai-chein was derived from the dried roots of C. stauntonii (Decne.) Hand.-Mazz.; and the Wan-ling-shu used locally in Taiwan was derived from the dried roots of C. taiwanianum Yamazaki.

<div><table cellspacing="0" cellpadding="0" align="center"><tbody><tr><td align="left" valign="top"><p>Since coconut is   one of the most recalcitrant species to generate <em>in vitro</em>, it is   necessary to study in detail about the cellular changes that occur during   somatic embryogenesis to enhance our knowledge about this phenomenon. In the   present study, coconut plumular tissues, the shoot meristem including leaf   primordia, were used as explants for <em>in vitro </em>regeneration studies.   Histological studies were carried out in different stages of plumule culture.   No noticeable growth was observed in 15 days old cultures. After 30 days,   meristematic cells could be identified. Abundance of meristematic cells,   foremost to the development of callus structures, was observed after 45 days.   After 75 days, globular friable calli were formed and histological studies   revealed the presence of meristematic centers which eventually formed somatic   embryos. The histological study of matured somatic embryos formed after 120   days of callus initiation showed a clear meristematic zone of parenchyma   cells, surrounded by vascular bundles. Histological studies, carried out for   certain abnormalities like compact calli, abnormal somatic embryoids with   rudimentary shoots and multiplied roots, revealed the presence of intact   cotyledonary leaves which seemed to inhibit the apical meristem development   of somatic embryoids. The presence of vascular bundles in the early stages of   callus formation might lead to the direct formation of meristemoids. These   results could aid future studies leading to enhanced control of the somatic   embryogenic process and greater efficiency of somatic embryo and plantlet   formation in coconut.</p></td></tr></tbody></table></div>

The root of Rotula aquatica is also called as pashanbed, belonging to the family Borogenaceae. It is widely distributed in India from kumaun to Assam and western to southern India.The medicinal values of plant lie in their component phytochemicals such as alkaloids, flavonoids, phenolic compounds and other nutrients like as amino acid, proteins, which produce a definite physiological action on the human body. The proximate values such as moisture content, ash value, extractive value, were carried out. The dried roots powder was subjected to successive extraction with different solvents like petroleum ether, benzene, chloroform, methanol, ethanol and water. Macroscopic as well as microscopic studies of any crude drug are the primary steps to establish its botanical quality control before going to other studies. Hence Standardization of crude drug plays a very important role in identifying the purity and quality of crude drugs. The present investigation reveals Standardization which include Moisture Content, Total ash, Acid insoluble ash, Water soluble ash, Water soluble Extractive value, Alcohol soluble Extractive value, Phytochemical screening, and further isolation and identification of Phytoconstituents.

The histological study showed that the retina of falcon"s eyeball was thin at the peripheryand ranges between 0.6-0.8 μ but it was thick at center 1.68-2.64 μ. The retina consists fromten layers: pigmented epithelium, rods and cons layer, external nuclear layer, externalplexiform layer, internal nuclear layer, internal plexiform layer, Gangilionic cells layer,neurofibres layer and internal limiting membrane layer. The ultra-structural study stated thatthe rods and cons layers contained single rods with single and double cons. The retinacharacterized by lacking of the oil droplets in the internal segments of rods with narrowexternal plexiform layer in order to form network connecting rods and cones, horizontal cells,bipolar cells and Muller's cells.

Flexor Tendons

As a part of a continuing study on the healing of flexor tendons, the effects of an antihistamine–antiserotonin compound (promethazine) were studied in 109 chickens. A form of standard surgical trauma to the intact flexor profundus tendon was devised, and the results of several different methods of administration of promethazine were compared. These studies indicate that minimal surgical trauma applied to an intact flexor tendon produces a marked reaction consisting of a degenerative phase, a phase of dedifferentiation, and a phase of regeneration and maturation. The histological studies reveal that such highly specialized intercellular substances as collagenic fibers and bundles, though non-living, are not inert and permanent structures. They can break down, completely disappear, and be reformed as a result of the reaction to trauma of specialized tenocytes and undifferentiated mesenchymal cells of the tendon and epitenon. The effects of an antihistamine (promethazine) are to prolong the phase of degeneration and loss of differentiation and, upon withdrawal, to accelerate the phase of growth and maturation. These effects vary with the dose and method of administration of promethazine.
