Over a period of approximately 30 years we have compared the frequency of Miner's phthisis in the coal mining areas of Aachen and the Ruhr area of Essen and have investigated a total of approximately 600 lungs with silicosis. In cases of silicosis grades II-III and III we found liquefaction in 36% of the callosities but in cases of silicosis I-II and II in only 4-7%. Liquefaction of callosities, or phthisis atra, was found slightly more often in the Ruhr area than in the area of Aachen.

A 46-year-old man with diabetes insipidus, hypothyroidism and hypocortisolism was found to have a tumor of the pituitary stalk. After transsphenoidal resection of the tumor substitution of cortisol and thyroxin was necessary. Pathological examination of the lesion revealed an extremely rare granulomatous infiltration classified as Gagel's granuloma (Langerhans' cell histiocytosis).

Twelve years after receiving radiation therapy with thorium X (280 microCi) for long-standing Bechterew's disease (ankylosing spondylitis) a 52-year-old man was found, by ultrasonography and computed tomography, to have a round mass, 11 x 12 cm, in the left lobe of the liver. Laparoscopy discovered coarse, discoloured nodes on the surface of the right and left lobes of the liver which histologically showed hepatocellular carcinoma. There were no known risk factor for liver carcinoma (like cirrhosis, positive hepatitis B serology, alcohol abuse, haemochromatosis or alpha 1-antitrypsin deficiency).

Microcystic pancreatic adenoma is an extremely rare tumor, arising in exocrine pancreatic tissue, which may lead to severe abdominal pain. To date malignant transformation has not been reported. There is a conspicuous, statistically significant, association of microcystic pancreatic adenoma with various other diseases.

The ability of acetaldehyde to initiate hepatotoxicity as evidenced by enzyme leakage, hepatic fat accumulation and histological alterations was studied in rats. Neither oral nor intraperitoneal treatment with acetaldehyde had any hepatotoxic effect, even following aldehyde dehydrogenase inhibition by disulfiram. This is probably due to the inability of exogenously added acetaldehyde to penetrate liver cell membranes.

Three epidermal tumors with squamous celled differentiation are described. Two appeared as epidermoid cysts, the other was a squamous cell carcinoma in a 100 year old female patient. Epidermoid cysts of the breast are rare compared to lesions occurring in other regions of the human body.

Six patients with radiation scars are described. In each case the diagnosis was confirmed histologically in five cases corresponding mammograms were available. The histological appearances of radiation scars are described and the radiological features are presented.

Abscesses of the liver represent the most common complications of amebiasis. In general they are treated non-surgically by the aid of Metronidazol. Complications, however, such as perforations, development of fistulas or septicemia may occur and necessitate surgical intervention.

A retrospective study of autopsies was performed on patients who died of ischaemic heart disease (IHD) in the industrialised Ruhr valley of West Germany. Groups were classified on the basis of the presence or absence of cardiac scar tissue, acute myocardial infarction and cardiac rupture. Severe coronary atherosclerosis was not a constant finding in IHD, and ranged from 57% of acute coronary insufficiency cases in women to 86% of recurrent infarction cases in men.

We describe a case of fatal gas gangrene of the uterus after an apparently normal term pregnancy in a 22-year-old woman. The patient died less than 15 h after the onset of symptoms, which consisted of a single episode of vomiting and increasing hypogastric pain. Hypotension, tachycardia and renal failure were the dominant clinical features.

Exposure of rats to a reduced oxygen tension (6% O2, 94% N2) for 6 h increased the serum enzyme and the histological lesions induced by carbon tetrachloride (CCl4). Hypoxia did not enhance the hepatotoxic response to paracetamol, allyl alcohol, bromobenzene or thioacetamide. No correlation was found between the changes in hepatotoxicity induced by hypoxia and those after treatment with ethanol.

In order to evaluate a possible primary or secondary immunologic response of the spleen after single or repeated in situ freezing of parenchymal organs such as liver and kidney within a four week period, light microscopic and cell kinetic investigations with tritiated thymidine were performed on spleens of non-germfree rats. Sham operations served as controls. The sham operations did not induce any significant morphological or cell kinetic changes in the splenic white pulp.

Six endotracheal applications of 15 milligrams of cadmium sulfide (CdS) given to rats at weekly intervals induce pneumoconiosis with massive adhesions. The same quantities of lead sulfide (PbS) given under the same conditions have much less effect, causing only the formation of fairly small fibrous nodules. The tissue reactions to CdS and PbS were studied morphologically (light and electron microscope) and enzyme-histochemically.

In the present work, light-microscopic changes in the renal arteries of the rabbit following instrumental compression for specific intervals are described: 1. Compression led to necrosis of whole layers of the vascular walls, which could already be observed under the light microscope after 3 h.--2.

In this paper we report the electronmicroscopic findings in a hepatocellular carcinoma of a 24 years old woman after taking oral contraceptives. We saw alterations of the nucleus (finger-like or finger-formed nuclei, nuclear invaginations and intranuclear vesicular membranbodies), changes of the mitochondries (number, polymorphy and osmiophil bodies) as well as changes of lysosomes (myelinshaped residualbodies). The observed and described changes are not specific for malignant tumors of the liver.

Case of unusual diffuse segmental lipomatosis of a part of the small bowel is reported. Other cases from the literature are compared to various pathological deposits of fat in the intestine. Aetiology, clinical signs, diagnosis and differential diagnosis, as well as surgical treatment, are discussed.

In continuation of our investigations of the wound healing process after cryonecrosis in the liver, kidney, spleen and stomach, the wound healing in the brain was studied under the same condition. Through a trepanation of about 3 mm diameter, the cortex of the parietal region of the cerebrum was frozen by a cryoprobe applied directly through the intact dura mater (-196degreesC/30s). The animals were killed at definite time intervals between 12 h and 21 days after freezing.
