International Standardized Nomenclature for Outbred Stocks of Laboratory Animals.

In accordance with the «Aims of ICLA» (ICLA Bulletin No. 26, March 1970) the Governing Board established in 1969 a Working Party to prepare an International Nomenclature System for Outbred Animals. The members were: Professor, Dr.

Estimation of countrywide NO emissions from wastewater treatment in Switzerland using long-term monitoring data.

Nitrous oxides (NO) emissions contribute to climate change and stratospheric ozone depletion. Wastewater treatment is an important, yet likely underestimated, source of NO emissions, as recent, long-term monitoring campaigns have demonstrated. However, the available data are insufficient to representatively estimate countrywide emission due to the brevity of most monitoring campaigns.

Specific versus nonspecific immune defense in the bumblebee, Bombus terrestris L.

Hosts vary in both their strength of response to a general immunological insult and in their specific susceptibility to different parasite species or different strains of the same parasite. The variation in the general immune response is considered a result of the costs imposed by selection on defended individuals. The variation in the specific response may originate from variation in host and parasite genotypes and is a requirement for frequency-dependent selection.

Epidemiology of atrazine.

Chronically exposed workers in chemical plants have revealed no increased incidence of benign or malignant disease attributable to atrazine. Some case-control studies showed a slight increase of non-Hodgkin's lymphoma (NHL) incidence while others were negative. Weighted evidence supports no causal association of malignant changes in farming populations with atrazine.

Toxicology of monocrotophos.

Monocrotophos is a water-soluble organophosphate insecticide with high oral and moderate dermal toxicity. The toxicologically relevant mode of action is the inhibition of ChE activities. The toxicity of organophosphate metabolites of monocrotophos is comparable with the parent compound.

[Treatment of sequelae of burns on the trunk].

The management of burn scars of the trunk is discussed, in respect of the specific problems related to different areas such as the axilla, thorax and back, the female breast and the perineum as well as the external genitalia. Special emphasis is placed on the different aspects of burn sequelae of the female breast with regard to pre- and postpuberty age. The prevention and therapy of the burn scar carcinoma are dealt with.

[Selective neurectomies in hemifacial spasm: an anatomo-pathologic discovery].

Today the treatment of choice in hemifacial palsy is selective neurectomy of the branches of the facial nerve. Palliative surgery has improved experience in the treatment of facial palsy. An anatomical finding is reported which could contribute to a better understanding of the etiology of facial spasm.

[Surgical treatment of malignant skin epitheliomas. Principles, methods, results].

From personal experience in the treatment of 655 patients with malignant epitheliomas of the skin, treated from 1966 to 1973 at the Department of Plastic and Reconstructive Surgery at the University Hospital, Innsbruck, the basic principles, methods, and results of treatment are reported. An adequate resection and a primary reconstruction is the method of choice. The clinical data and follow-up observations are analyzed and special types of treatment and indications are discussed.

Detection of recurrence of large-bowel carcinoma by radioimmunoassay of circulating carcinoembryonic antigen (C.E.A.).

The usefulness and limitations of the carcinoembryonic antigen (C.E.A.
