Regulation of the delayed hypersensitivity reaction in the lung reflected as mononuclear, mast cell and mucus cell appearance after T helper cell depletion and adoptive transfer

Epicutaneous sensitization with picrylchloride (PiCl) induced a strongly delayed hypersensitivity (DH) reaction in mice. Local challenge in the airways of these mice resulted in increased numbers of mononuclear cells, mast cells and mucus cells. Depletion of T helper cells in vivo by treatment with monoclonal antibody (GK 1.5) inhibited the DH reaction. This treatment also resulted in a decrease in the number of mononuclear and mucus cells in the lung after intranasal challenge. The DH reaction was transferred to recipients with immune lymph node cells and spleen cells from mice sensitized epicutaneously with PiCl. The recipient mice also showed a slight increase in the number of mononuclear cells in the lung after intranasal challenge. These results indicate that T cells are not only involved in the DH reaction but also in the accompanying lung reaction.     

Mechanism of testicular atrophy induced by di-n-butyl phthalate in rats. Part 1

Repeated oral doses of di-n-butyl phthalate (DBP) to male rats caused a decrease in testicular fructose and glucose and a sloughing of the germ cells on the first day of treatment. On day 2, more severe sloughing was seen and was accompanied by decreases in testicular iron and zinc levels and increases in the level of inositol and cholesterols. The sloughing was followed by atrophy, accompanied by dissociation of the germ cells from the Sertoli cells and reduction of triglycerides, cholesterols and phospholipids containing choline and ethanolamine residues in the testis.     

A case of leiomyosarcoma of the prostate

A 50-year-old man with the symptom of anal pain was treated by pelvic exenteration, ileal conduit diversion and artificial anus. The pathologic diagnosis was leiomyosarcoma of the prostate. At 5 months post-operatively, the patient had no evidence of metastasis or recurrence.     

Predicting weight loss in patients with massive obesity after jejunoileal shunting

Postoperative decrease of the body mass was studied in 105 patients with massive obesity subjected to operation of jejunoileoshunting. Loss of the body mass was proportional to its initial value, inversely proportional to the length of the functioning portion of the ileum. In men the degree of postoperative loss of the body mass was more considerable than in women.     

Availability of NSAIDH beta-cyclodextrin inclusion complexes

The diffusion of a series of non steroidal antiinflammatory drugs through a silicone rubber membrane has been studied from suspensions both of the free and beta-cyclodextrin complexes forms at different pH values of the medium. Higher diffusion rates of the complexed forms as compared with the free ones and a rate-limiting effect of the apparent stability constant in the diffusion of the complexes were observed.
