The effect of grain component of the diet on the response of turkey poults to vitamin D3 and penicillin.

Three experiments were conducted with turkey poults to study the effects of the grain component of the diet (corn or rye), added fat, penicillin or extra vitamin D on growth and bone ash. In the first trial, where rye replaced corn in the diet, growth was depressed and the pults were rachitic before two weeks of age. Adding fat or penicillin to the rye containing diets significantly improved growth and increased bone ash. In the second trial, adding extra vitamin D3 or penicillin to a diet with rye increased both growth and bone ash. Diets containing either corn or rye were used in the third trial and the results again showed that extra vitamin D or penicillin markedly improved growth and bone ash when added to the diets with rye but did not significantly increase growth of poults on the diets with corn. Bone ash of turkeys fed the corn diets was significantly increased by a combination of extra vitamin D3 and penicillin.

Variable rachitogenic effects of grain and alleviation by extraction or supplementation with vitamin D, fat and antibiotics.

Three experiments were conducted using day-old broiler type chicks to determine the effect of different cereal grains on vitamin D3 utilization and to investigate the effects of rye, corn, wheat and triticale as the cereal grain component of the diets on the development of a rachitic condition in chicks. Rye was submitted to acid treatment and water extraction in an attempt to destroy or isolate the rachitogenic factor. Results showed that with chicks fed a diet containing 200 I.U. of vitamin D3 with corn as the grain, mineralization of their bones was normal. Growth and bone ash were depressed when rye replaced corn in the diet. These effects were partially reversed when either fat or procaine penicillin was added to the diet, and comppletely prevented with a high level of vitamin D3 (2,000 I.U./kg.). In another experiment, triticale depressed bone ash even though it did not affect body growth to the same extent as rye. Our results indicate that the factor responsible for the rachitogenic condition of rye-fed chicks can be removed by water extraction of this grain or partially destroyed by acid autoclaved treatment. A combination of acid autoclaved treatment and penicillin supplementation prevented the depression in bone ash.

[Conservative and surgical treatment of pericarditis--our experience].

Methods and results of both conservative and invasive therapy of pericarditis were analysed in the group of 30 patients. An emphasis was on successful treatment of mild (idiopathic) pericarditis and efficiency of the early started, combined pharmacotherapy (tuberculostatics + corticosteroids) of pericarditis of tuberculous etiology. A stress is on marked immediate efficacy of surgery in case of cardiac tamponade, independent on its etiology, with simultaneous recommendation of ultrasound-guided pericardial sac paracentesis. Survival rate in patients with malignant pericarditis is relatively low.

[Identification of a limited form of small cell lung cancer among 103 patients pre-selected for chemotherapy combined with surgery].

Between Nov. 1981 and Nov. 1987 103 patients preselected for chemotherapy combined with surgery, therefore with local extension within homolateral mediastinal lymph nodes, with no signs of remote metastases, PS greater than or equal to 70, with no contraindication for resectional surgery including pneumonectomy, no diabetes, no prior treatment underwent first staging. Staging included: case history, physical examination, full blood count, biochemical tests (alkaline phosphatase, SGOT, GGTP, LDH), CEA, X-ray assessment including CT scan of the chest, bronchoscopy, peritoneoscopy, liver scan (US was not routinely used at the beginning), bilateral bone marrow trephine biopsy, and bone scan. Staging was discontinued when secondaries were detected in one, the more so as in two organs or systems (25 pts), and/or bronchoscopic contraindication for thoracotomy (11 pts), and this group of patients was out of the study. To 67 patients chemotherapy was given and after 3 courses these patients were reevaluated. In 21 patients PD, NC or CR was found. Forty six patients with PR underwent supplementary staging procedures: CT of the brain, CT of the upper retroperitoneal space and liver. Metastatic sites were found in 7 patients. Limited disease was identified in 39 patients. Limited-stage disease can be determined only after exclusion of extensive disease on the ground of: case history, physical assessment, X-ray of the chest (PA + lateral) + CT chest scan, bronchoscopy with biopsy or cytology, and outside the chest: 1. bone marrow trephbine biopsy and bone scan--bone marrow and skeleton, 2. CT head scan--brain, 3. CT abdominal scan--upper retroperitoneal space and liver.
