The simultaneous determination of acid phosphatase and citrate concentration in the seminal fluid obtained from 16 patients with prostatic adenoma showed normal values, 6 patiients with prostatic carcinoma (cytologically and histologically verified) however extremely low values. The difference between persons with prostatic cancer and those with adenoma became particulary obvious with both experimental results evaluated in the way of a twodimensional diagram. This clear separation of both clusters by the simultaneouse estimation of both biochemical parameters may possible get useful diagnostic significance.

Two cases of urethral nephrogenic adenoma involving the prostate are described. A diagnosis of prostatic carcinoma was raised in both cases and was seriously entertained in one of them. The patients, who were 65 and 68 yr old, underwent transurethral resection because of difficulty voiding; both had had a prior similar procedure. Microscopic examination in each case showed small tubules and clusters of cells in the fibromuscular stroma of the prostate. In one case the lesional cells had abundant clear cytoplasm, and in both cases some of the nuclei had prominent nucleoli. In each case a minor component of the cystic pattern of nephrogenic adenoma was also present. Features pointing to a diagnosis of nephrogenic adenoma were a morphology that was diagnosis of nephrogenic adenoma were a morphology that was focally characteristic of that lesion, an origin from overlying prostatic urethra in both cases, and negative immunohistochemical staining of the lesional cells for prostate-specific antigen and prostate-specific acid phosphatase. These cases illustrate that nephrogenic adenoma occasionally involves the prostate and in these cases can potentially be confused with prostatic adenocarcinoma.

Studies of surgery for symptoms of bladder outlet obstruction in men suggest that a possible higher long-term mortality occurs in patients having transurethral prostatectomy compared with patients having an open prostatectomy. It is the purpose of this study to determine if intraoperative factors affect the long-term survival of patients having transurethral prostate resection for benign prostate hypertrophy. In 158 consecutive patients having transurethral prostatectomy for benign adenoma who were followed for eight years, 28 patients died during the follow-up period. In comparing those patients who are alive with those patients who have died, there was no significant difference at the time of surgery in intraoperative irrigant absorption as indicated by changes in serum sodium and there was no significant difference in the intraoperative absorption of prostate tissue substances as indicated by changes in serum acid phosphatase. The only factor in this study associated with long-term survival was age of the patient at the time of surgery with older patients having a higher long-term mortality. This study suggests that age of the patient rather than intraoperative factors is associated with long-term survival following transurethral prostatectomy.

The distribution of enzymes and laminin was examined in ileal tissue from pigs suffering from intestinal adenomatosis to reveal the nature of the lesion. A disruption of the normal and specific pattern of distribution was found. Thus, the normal ileal epithelium was characterised by brush border enzymes: alkaline phosphatase, magnesium-dependent adenosine triphosphatase (Mg-ATPase), fluoride resistant acid phosphatase and 5'-nucleotidase; enzymes of the basolateral border: Mg-ATPase; and cytoplasmic enzymes: beta-glucuronidase, non-specific esterase and acid phosphatase. Subepithelial fibroblasts seemed to be characterised by 5'-nucleotidase. Laminin was present as a continuous band under the surface and crypt epithelium, somewhat thicker in the former. In contrast, the branching proliferating crypts of intestinal adenomatosis largely lacked enzymes characteristic of both villus and crypt cells. Reactions for the subepithelial components, laminin and fibroblasts were also reduced. The deficient differentiation of the epithelial as well as subepithelial components in porcine intestinal adenomatosis distinguish the condition from crypt hyperplasia and indicate an adenoma-like character.

Serum acid phosphatase levels were measured in 402 patients after transurethral resection of the prostate for benign adenoma. All patients had normal preoperative serum acid phosphatase levels (less than 0.8 IU/L) and the tissue specimen was histologically benign in all patients. Ninety-three patients (23%) showed normal postoperative serum acid phosphatase levels, while 309 (77%) showed postoperative elevation of serum acid phosphatase. One hundred forty-eight patients (37%) had postoperative levels higher than 5 IU/L. Significant elevation of serum acid phosphatase may follow transurethral prostate resection in patients having no evidence of malignancy.

A slow-growing tumor on the dorsum of the right foot of a 25-year-old female had features that corresponded to papillary eccrine adenoma. The grouping of this entity under the term "tubular apocrine adenoma" in a recent edition of a textbook led to further study of this case in the form of enzyme histochemistry and electron microscopy. The tumor was positive for amylophosphorylase and negative for acid phosphatase, and on electron microscopy showed complex intercellular membrane interdigitation and a possible intercellular canaliculus. No features of apocrine differentiation were found, and we feel that this tumor is distinctly eccrine in its differentiation. The similarity of these two ostensibly separate entities, and the opinion of some authors that intermediate differentiation may be possible in adnexal tumors, would favor them being grouped under the single term of "tubulopapillary hidradenoma," with apocrine or eccrine differentiation as the case may be.

Biopsy specimens from 29 adenomas, 17 adenocarcinomas, and 6 synchronous adenomas in cancer patients and from uninvolved mucosa of all main segments of the large bowel were examined histologically and assayed for a series of organelle marker enzymes. Six enzymes--lactase, sucrase, alkaline phosphatase, 5'-nucleotidase, acid phosphatase, and N-acetyl-beta-D-glucosaminidase--showed less activity in adenomas than in adjacent uninvolved mucosa and in specimens from controls. Cancer tissue had higher gamma-glutamyltransferase and lower lactase, alkaline and acid phosphatases, and N-acetyl-beta-D-glucosaminidase activities than specimens from uninvolved mucosa in cancer patients and control patients. Enhanced alkaline phosphatase and N-acetyl-beta-D-glucosaminidase activities were seen in uninvolved mucosa of cancer patients as compared with those of adenoma and control patients. Evidence has been found for multienzyme analysis to identify adenomas with signs of malignant transformation and carcinomas with poor prognosis.

Enzyme histocytochemical staining including alkaline phosphatase, acid phosphatase, 3 beta hydroxysteroid dehydrogenase and 11 beta hydroxysteroid dehydrogenase was studied in human adrenocortical adenomas associated with primary aldosteronism. Histochemically, these enzyme activities were weaker in clear cell type adenomas than in the normal human adrenal cortex. While compact cell type adenomas showed stronger enzyme activities than the clear cell type adenomas. Electron microscopic localization of alkaline phosphatase was mainly observed in plasma membrane at the intercellular sites. Occasionally, this enzyme activity was also observed in the mitochondrial outer membrane, mainly in compact cells. The significance of these enzymes in the adenoma cells is discussed.

In 46 patients with primary hyperparathyroidism, in 21 non-dialysed patients with advanced renal failure, and in 52 patients on hemodialysis, a significant positive correlation was found between bone isoenzyme of serum alkaline phosphatase and plasma tartrate resistant acid phosphatase. In primary hyperparathyroidism, a significant positive correlation was found between the radiological degree of osteodystrophy and the biochemical parameters of bone remodelling. After removal of the parathyroid adenoma, only the tartrate-resistant acid phosphatase decreased to normal limits. Plasma tartrate resistant acid phosphatase was most significantly influenced by serum immunoreactive parathyroid hormone levels. In chronic renal failure, bone isoenzyme of serum alkaline phosphatase was most significantly influenced by serum immunoreactive parathyroid hormone levels, by hypocalcemia and by duration of hemodialysis. The results confirm that in hyperparathyroidism the extent of the whole-body rates of bone resorption and formation are approximately equal. The biochemical parameters can be used for serial assessment of the course of the disease but are not specific for diagnosis.

The clinical application of an enzyme-immunoassay for the determination of the prostate-specific acid phosphatase is reported. By this method 615 plasma probes of patients with prostata adenoma, prostatitis, prostatic cancer and other urological cancer were investigated. Whereas the enzyme-immunoassay showed good correlation with the follow-up of prostatic cancer especially when metastases grow on, the test is not yet sensitive enough to find out early prostatic cancer with reliable accuracy.
