Comparative activity of ifosfamide and cyclophosphamide.

Antitumor activity (increase in lifespan and cure) was greater for ifosfamide (IFO) in several experimental tumors, some of which were primarily resistant to cyclophosphamide (CYC). IFO has been shown to be active in anthracycline-resistant and in adriamycin/cisplatin-resistant sublines of an Ehrlich ascites tumor, as well as in tumor cells primarily resistant to CYC. The few comparative controlled clinical trials available suggest superior single-agent activity of IFO compared with CYC in soft tissue sarcoma and ovarian cancer. Combination chemotherapy with IFO has been effective in second-line treatment of sarcomas, malignant lymphomas, lung cancer, and testicular cancer, most of them pretreated with or refractory to CYC. Although it is difficult to obtain clinical proof that there is no cross-resistance between IFO and CYC, IFO has been shown to be active in multirefractory malignant lymphomas, in small cell lung cancer not responding to adriamycin, vincristine, and etoposide, and in soft tissue and bone sarcomas. Testicular cancer and pancreatic cancer are some of the tumors in which IFO activity is currently being evaluated and in which CYC has so far failed to show sufficient clinical activity. More comparative controlled clinical trials are needed in ovarian cancer, breast cancer, malignant lymphomas, sarcomas and cervical cancer, in which IFO has already shown sufficient single-agent activity. Due to its lower level of cross-resistance with a variety of heterocyclic products, but also with other alkylating agents, in addition to its use in induction chemotherapy, IFO is an important second-line agent in many clinical situations.

[Treatment of bronchitis with cefaclor (Panoral) (author's transl)].

14 patients from the Allergy Unit of an outpatient clinic suffering from acute exacerbation of chronic bronchitis and 13 outpatients with acute bronchitis were treated with 250 mg cefaclor (Panoral) 3 times daily per os for 5 days. 59% of the organisms isolated from cefaclor-sensitive sputum at the time of prominent clinical symptoms were resistent to tetracycline, 53% of them were resistant to penicillin, and 37% were resistant to ampicillin. 12 out of the 14 patients with acute exacerbation of chronic bronchitis became asymptomatic, and no organisms could be detected in the sputum of 13 out of the same 14 patients two days after cessation of cefaclor treatment. In 12 out of the 13 patients with acute bronchitis, the acute clinical symptoms disappeared and in 11 out of the 13 patients the initial sputum organisms were two days after stopping cefaclor treatment.

[Hypersensitivity to antibiotics: Frequency, risks, cross-allergies (author's transl)].

The present paper gives a systematic review of the clinical manifestations of allergic reactions and the underlying immunological mechanisms. Attention is drawn to the relatively high proportion of cases of anaphylactic shock and serum disease related to the total number of cases of allergic reaction, and to the diagnostic techniques available for detection of sensitization towards antibiotics. Structural allergenicity is mentioned, using penicillin allergy as an example. The frequency of allergy to several antibiotics and the frequency of cross-reaction between penicillins and cephalosporins reported in the literature are discussed critically.

[Nutrient supply of health and sick fluid fed calves].

In the department for calves being fed with fluid feed of a specialised enterprise for calf rearing the daily intake of fluid feed (skim milk improved with milk substitute), concentrated feed and hay of a total of 341 female animals and the daily intake of energy and protein was calculated thereof. The average consumption of nutrients of the 206 healthy calves was compared with some international and national norms for the demand of nutrients. The comparison with some international values of demand and the results of the partial correlation analysis between energy and protein intake and live weight increase showed that the applied nutrition regime (particularly the kind of fluid feed) has resulted in an excessive supply of the calves with proteins and an insufficient supply with energy. This could not be realised from the GDR nutrients norm for the raising of calves published in 1976. Based on theoretical considerations and some recent findings of the science of nutrition we derived values of the protein and energy demand of our own. Subsequently an attempt is made to assess the supply with nutrients for sick calves.

[Effect of diseases on the nutrient intake by suckling calves].

An energy and protein intake test was applied to 341 female nursed calves under production conditions. Their daily intakes of skim milk enriched with milk substitute, fodder concentrates, and hay were recorded and their daily energy and protein intakes calculated. Their feed consumption was characterised by cumulative nutrient intake curves, depending on the time of foremilk feeding (K-I-period). Energy and protein intake figures were related to the findings obtained from daily health control, with the view to defining the effects of pneumonia or diarrhoea on feed intake. Both diseases were found to cause significant reduction in nutrient intake, depending on the given type of disease and severity, with their negative impact having been most markedly shown in the context of dry feed intake. The delay caused to the development of dry feed consumption by diseases of the respiratory and digestive tracts was many times longer than the time of the clinical course. The above observations provided some cues for conclusions regarding the approach to be taken by the veterinarian to diagnosis, therapy, and rehabilitation of affected calves. Certain concepts were derived from the findings as to how to feed calves to forestall developmental disorders.

[The use of biotechnology in animal breeding].

Biotechnological techniques are extensively used in dairy breeding programs. Thus, artificial insemination and embryo transfer (and associated techniques) constitute an integral part of modern breeding programs. In pig breeding, embryo transfer is mostly restricted to special problem areas because of its high costs. Currently this technique is used for the exchange of genetic material on an international level, for the creation of specific pathogene free herds, and in connection with cryoconservation for the setup of embryobanks in the context of the preservation of genetic resources.
