In 26 dogs, pH and K+-concentration measured continuously on the surface of the liver. The same decrease of pH and increase of the K+-concentration was found after ligation of the hepatic artery as when arterial and portal circulations were suspended. Reperfusion restored normal conditions even after 45 minutes of circulatory arrest. Arterialization of the portal vein abolished the effect of the ligation of the hepatic artery.

The diagnostic problems and treatment of acute suppurative nephritis are discussed on the basis of 146 patients. The biological properties of the pathogens isolated from urine and their manifestation with clinical symptoms are discussed. The role of incorrectly prescribed antibiotics in changing the characteristic symptoms and thus making diagnosis difficult is stressed. It appears from the material that in 20% of the operated patients all x-ray and laboratory tests gave negative results, despite the fact that in the course of operation abscesses were detected under the renal capsule. In 60% of the cases x-rays supplied reliable information for the indication of surgical intervention. The history of fever and shaking fits and the progression revealed by careful observation of the patients are considered the most important information needed for deciding for surgery.

The effect of low-output He-Ne laser rays on the survival of mouse lymphoma P388 cell cultures was studied on the basis of the colony forming ability. Irradiation with 1.3 and 9 joule of 5 and 10 mW He-Ne lasers, respectively, seemed to cause a relatively low cell necrosis. The survival curve did not show the shape characteristic of ionizing radiation.

In transvesical prostatectomy haemostasis was achieved by the application of a modified U-shaped needle. The method was applied in 34 patients. It is suggested that the method can advantageously be applied when bleeding starts not from the loge-edge, but from the stump of the urethra or from the base of the loge. The bladder was closed by introduction of a balloon catheter and an epicystomic drain. Though the new method ensures additional advantages, it does not solve all the problems arising in connection with prostatectomies.

The use of camera renography under experimental conditions is described. The conductivity of the ileo-ureter formed by various surgical techniques in 24 dogs and the function of the operated kidney were studied. The non-invasive examination lasted for 20 minutes and was performed with two different labelled drugs (131I-iodohippurate and 99mTc-DTPA) and a gamma-camera calculator system. The results have shown that the ileo-ureter provided with a direct single layer uretero-ileal anastomosis ensured best the transport of urine and so it seems to be most promising for human application.

Seven hundred and fifty transvesical prostatectomies are evaluated from the aspect of complications. The method is used for the removal of adenomas of more than 30 g weight. Consequently, it is considered important to exactly determine the size of the adenoma and its relation to the neighbouring organs. The decrease in the number of complications, as well as the shorter time of operation and of postoperative care are attributed to the surgical method modified by the authors which involves the use of synthetic multifilament continuous suture pulling together the edges of the base of the prostate, a three-bore catheter placed with its balloon into the bladder, washing of the bladder in a closed system, mobilization of the patient on the first postoperative day, application of easily absorbed synthetic threads and early removal of the catheter. In order to lower the number of complications, the importance of the properly chosen anaesthesia is stressed.

The case of a woman with angioleiomyolipoma is reported. In the light of published data a brief review is presented on the aetiology, pathology and clinical aspects of this extremely rare disease. Angioleiomyolipoma is a benign disease which can be cured by removal of the kidney. In the case at issue, there occurred no tuberous sclerosis in the patient.

On the basis of studies performed during the past two decades primary malignant melanoma can now be recognized in over 90% of the cases. The clinician, the nurse and even the patient can be taught to recognize the lesions early while histology is able to reveal the important prognostic factors, such as growth phase, depth of invasion and tumour thickness. This allows to identify the patients at high risk of developing occult metastases in regional lymph nodes. Early diagnosis and surgical treatment of melanoma are now the only acceptable approach and therefore all physicians must be on the alert for the condition.
