The following results relating to the anatomy of the mucous membrane of the alimentary canal were obtained in the laboratory of the Brown Institution. The researches were carried out under the direction of Dr. Klein. 1. Connective-tissue corpuscles amongst the epithelium .—In specimens hardened in chromic acid and alcohol and stained in hæmatoxylin, structures are constantly seen among the columnar epithelium of the intestinal tract in many animals (as monkey, sheep, cat, dog, rat, rabbit) which belong to the connective tissue. These are :— (1) a delicate reticulum, which is continuous with that formed by the most superficial layer of connective-tissue corpuscles (the basement membrane) ; (2) round nucleated cells, exactly similar to those of the mucosa.

Halys dentatus is well known sap sucker living under the bark and having the reputation of affecting nutritional supply of their host plants. Dichlorovos (2,2-dichlorovinyl dimethyl phosphate) is an organo-phosphorus compound previously used for controlling crawling and flying insect pests. In the present study dichlorovos has been tested as systemic poison for checking its lethality against plant bug Halys dentatus. The oral application has found to be effective, as it disintegrates components of gastro-intestinal tract affecting vitality of test individuals. The adult plant bug when treated with dichlorovos, alteration in histological structures of ventriculus has been observed. In most of the cases alteration in shape of ventricular components has been noticed; basement membrane has found to be collapse while longitudinal and circular muscles layers were also disrupted. The cell boundaries of epithelial cells found to be busted and secretory cells become denatured; nuclei were found to be stained intensely as compared with untreated histological sections

E Cadherin

The distribution of epithelial E-cadherin, basement membrane type VII collagen, and underlying connective tissues fibronectin were investigated immunohistochemically and compared in normal palatal mucosa and in denture-related stomatitis (DRS) derivatives using monoclonal antibodies.Biopsies of palatal mucosa were obtained from twelve patients enrolled in this study, 8 with type II DRS and 4 with healthy mucosa. Our findings bring to the fore, using the expression of three components (E-cadherin, collagen type VII, fibronectin), the continuities of the disorder among epithelial, basement membrane and connective tissue in the case of DRS. In type II denture-related stomatitis, we found an expression of E-cadherinin all the strata of epithelia, and the diffuse and strong expression of type VII collagen at the interface between connective tissue and epithelial cells with discontinuities in BM. The strong expression of fibronectin in underlying connective tissue with penetration in some areas of the palatal mucosa may be an early consequence of advanced DRS. Nevertheless; no single change is pathognomonic of this inflammatory process. In normal tissues (healthy clinical aspect), E-cadherin was found to be restricted to the upper strata of the epithelia, and type VII collagen revealed thin linear staining in the basement membrane and fibronectin in underlying connective tissue combined epithelia. In the case of denture-related stomatitis DRS, these three markers reflect the immunohistological modifications from the superficial layer of the epithelium to the lamina propria.

Human anatomy is the science where human body structures are designed to enable complete physiological action thus establishing homeostasis of the human body. Acharya Sushruta had a keen observation about the human body reflecting that without the absolute knowledge of Rachana Sharir. Chikitsak cannot be considered an expert. In Ayurveda, the part of G.I.T. is mentioned in Koshthanga by various Acharya. These Koshthanga are Aamashaya, Pakwashaya, Purishdhara, Uttarguda, Adharguda, Kshudrantra etc. which are situated within the koshtha. In modern anatomy, G.I.T. or Alimentary canal includes all the structures between the mouth and anus, forming a continuous passageway that includes the main organ of digestion, namely the stomach small intestine and large intestine, each part of the Gastric intestinal tract is adapted to its specific function. The 'oesophagus' function primarily to conduct food rapidly from the pharynx to the stomach mixing along with the digestive juic- es, carrying out partial digestion and then propelling the food into the duodenum is the function of the stomach small intestine is designed for complete digestion and absorption of nutrients. Absorption of water and electrolyte from the chyme to form solid faeces is the function of the large intestine. Pakwashaya is the main organ related to the site of Vata Dosha, Purishvaha srotas, Purishdhara kala, Koshthanga and Aashaya. Pakwashaya plays an important role in formation of urine and digestion of food. Keywords: Pakwashaya, Purish

The material of the authors consists of 5 cases of gonorrhea that died from accidental causes, 1 case of amputation and 3 cases. extirpation of the paraurethral course. Conclusions: the gonorrhea process is played out in the epithelium and connective tissue of the genitourinary tract and has an exudative-proliferative character. The inflammatory infiltrate consists of lymphoid cells, plasma cells, leukocytes, and eosinophils. The squamous epithelium is not an obstacle to the penetration of infection this is clearly seen when studying the process in the paraurethral passages. The penetrated deep into the gonococcus are phagocytosed by lecocytes in the surface layers of the submucosa. Metaplasia of columnar epithelium in squamous and transitional, can be in any part of the genitourinary tract and can be detected before the onset of gonorrhea. Litreitis is not necessary for gonorrhea. Prostatitis can be without vesiculitis.

Primordial Odontogenic Tumor

Primordial odontogenic tumor (POT) is a benign mixed odontogenic tumor comprised of a loose connective tissue with a similar morphology with dental papilla and exhibiting in its periphery the presence of a columnar epithelium. POT occurs in young patients and typically is associated with an unerupted tooth, with the mandible being the main anatomic site of occurrence. The present manuscript is aimed at describing a new case of POT and reviewing the main biologic findings related to this odontogenic tumor.

Subcutaneous Connective Tissue

A lymphangiosarcoma with metastases was found in a horse that presented with respiratory distress and edema in the ventral thorax and abdomen. The necropsy revealed diffuse edema in the subcutaneous connective tissue. Mediastinal, mesenteric, iliac, and renal lymph nodes were enlarged and white with soft, yellowish necrotic areas. Histologic examination revealed numerous channels and disorganized vessels lined by large polyhedral, polymorphic cells. Tumor metastases were observed in the spleen, lungs, and kidneys. Immunohistochemical evaluation of the tumor cells demonstrated positive staining for factor VIII, vimentin, and keratin. Laminin was scarce, and collagen IV staining was negative, consistent with a discontinuous or absent basement membrane.

Bowman's Capsule

This study comprises some observations about the structure of the connective tissue of the basement membrane and interstitium in some normal, post-natal human kidneys. The basis of the basement membrane is mainly a reticular, homogeneous membrane that belongs uniformly to both Bowman's capsule and the wall of the renal tubule. Outside it in the capsule is a durable collagenic membrane whose development must be considered and evincement of functional adaptation under the pressure conditions of the cavity. In renal tubules there is no such well-defined outer membrane, but in them the basement membrane has in addition collagenic traits to some extent and is thus reticular-collagenic when examined as a whole. The renal tubules are surrounded by a dense, spiraling reticular network of fibres which attaches to the connective tissue of the interstitium where fibrocytes are scarce. The network extends all the way around the renal corpuscle. There is no elastic tissue at all in the basement membranes.

The following is an account of a research undertaken in the laboratory of the Brown Institution in July 1873, under the direction of Dr. Klein, and carried on there under his direction until October 1874. During the last year it has been continued in the physiological laboratory of St. George’s Hospital. Chapter I. The minute anatomy of the mucous membrane of the intestine, and the method of fat-absorption. In this chapter I propose first to state very briefly the result of my researches on the structure of the intestine and the method of fat-absorption; secondly, to relate the his­tory of these subjects; and, finally, to give a detailed account of this research.
