The biological diagnosis of prostatic carcinoma in relation with benign prostatic hypertrophy is essentially realized by the evaluation of plasma PAP or medullar PAP, the increase of which rises to 70% of the cases. This evaluation contains also other biochemical markers such as CK-BB, glucose-6-phosphate dehydrogenase, LDH 5 or alkaline phosphatase. The elevation of urinary polyamines is also correlated with the evolution of carcinoma. Other markers have been recently described such as PSA, useful both by evaluation in serum and by its identification on biopsy in histopathology. This exploration could be completed by the evaluation of androgenic receptors and of circulating androgens.

A herbal tea (called an abafado in Brazil) prepared from the dried leaves of lemongrass was administered to healthy volunteers. Following a single dose or 2 weeks of daily oral administration, the abafado produced no changes in serum glucose, urea, creatinine, cholesterol, triglycerides, lipids, total bilirubin, indirect bilirubin, GOT, GPT, alkaline phosphatase, total protein, albumin, LDH and CPK. Urine analysis (proteins, glucose, ketones, bilirubins, occult blood and urobilinogen) as well as EEG and EKG showed no abnormalities. There were slight elevations of direct bilirubin and of amylase in some of the volunteers, but without any clinical manifestation. These results taken together indicate that lemongrass as used in Brazilian folk medicine is not toxic for humans. The eventual hypnotic effect of lemongrass was investigated in 50 volunteers who ingested samples of lemongrass and a placebo under double-blind conditions. The parameters (i.e. sleep induction, sleep quality, dream recall and rewakening) did not show any effect of lemongrass as compared to the placebo. Eighteen subjects with high scores of trait-anxiety were submitted to an anxiety-inducing test following taking lemongrass or placebo under double-blind conditions. Their anxiety levels were similar, indicating that the abafado of the plant does not have anxiolytic properties. It is concluded that lemongrass, one of the most popular Brazilian herbal medicines, used for its alleged CNS-depressant effects, is atoxic but lacks hypnotic or anxiolytic properties.

Clinical and laboratory studies have confirmed the efficacy of alpha-fetoprotein (AFP) and human chorionic gonadotropin (hCH) as tumor markers in the diagnosis, monitoring and assessment of prognosis in cases of testicular tumor. Serum AFP level is positive in 75% of yolk sac tumors, 70% of embryonal carcinomas and 62% of teratomas. All cases of choriocarcinoma show elevated serum hCG. In the treatment of prostatic cancer, prostatic acid phosphatase (PAP), prostatic-specific antigen (PA) and gamma-seminoprotein (gamma-Sm) are important serum markers, and the RIA method has improved their specificity and sensitivity. These markers are also correlated well with therapeutic efficacy. Especially, improvement of the serum PAP level in patients with stage C and D cancer indicates prolongation of survival time. Over 90% of the metastatic lesions of prostatic cancer are encountered in the skeletal system. Thus, serum alkaline phosphatase and urinary hydroxyproline are considered to be useful markers for indicating bone involvement. In other urological malignancies, there are no specific tumor markers. As non-specific markers for renal cell carcinoma, ESR, LDH, CEA, alpha 2-globulin, haptoglobin, fibrinogen and various hormones have been investigated. In the treatment of bladder cancer, it is important to distinguish the malignant potential of the tumor. From this viewpoint, various immunohistochemical investigations and flow cytometric analysis are now in progress. It is expected that some of the findings of the studies could prove to be of clinical use in the near future.

In 40 patients (17 male, 23 female, median age 57 years) with the presumptive diagnosis of primary (essential) thrombocythemia (PTH) according to the diagnostic requirements of the Polycythemia-Vera-Study-Group (PVSG) a follow-up study and a histological evaluation of initial trephine biopsies of the bone marrow were performed. Thorough review of the hematological data during the lengthy course of disease (observation time ranging from 1.5-10.5 years) and the histomorphology of the bone marrow implied a discrimination into two groups of patients. Group I patients (n = 26; 10 male, 16 female) were compatible with PTH according to our follow-up studies. Group II patients consisted of 14 cases (7 male, 7 female) which suggested retrospectively early hyperplastic stages of agnogenic myeloid metaplasia (AMM) with concomitant thrombocytosis. In PTH (group I patients) there was a sustained elevation of the platelet count lasting for several years accompanied by stable other blood values. Early AMM (group II patients) was characterized by an insidious decline of the initially elevated thrombocyte count, starting in a few patients already 4-6 months after admission. In AMM there was further an increase in hepatosplenomegaly observable together with the level of LDH and the score of the leukocyte alkaline phosphatase, and finally an evolution of a leukoerythroblastic blood picture could be noticed. Initial histopathology of the bone marrow revealed a profound proliferation of a not severely dysplastic megakaryopoiesis in group I patients (PTH) and a normal content of reticulin fibers. In early thrombocythemic AMM (group II patients) conspicuous abnormalities of megakaryocytes were accompanied by a slight to moderate increase in argyrophilic fibers and a left-shifted neutrophilic granulocyto- as well as erythropoiesis. These differences of certain histomorphological features could be substantiated by morphometric analysis. Our findings suggest that even the rigid requirements for the diagnosis of PTH as proposed by the PVSG may not be sufficiently restrictive to exclude patients with early hyperplastic stages of thrombocythemic AMM.

We studied the testis of Wistar rats weighing 280-300 gms. following the administration of a single, acute intracardiac dose of methionine-enkephalin (100 microliters of 50% met-enkephalin solution), or a chronic intramuscular dose (50 microliters of 40% met-enkephalin solution). Rats were sacrificed at 15, 30 and 60 minutes following acute injection. Those on chronic treatment were injected once daily for 10 or 20 days. For the study, we utilized 105 male Wistar rats; 30 comprised the control group, and 75 comprised the study group. The following staining methods were used: 1) succinate dehydrogenase, 2) lactate dehydrogenase, 3) ATPase, 4) acid phosphatase, 5) alkaline phosphatase. We observed marked histoenzymological changes in the rat testis. Particularly noteworthy was a marked change in the energy pathways consisting of a decreased activity of aerobic pathways (decreased SDH activity), increased anaerobic activity (increased LDH activity), and consequently, decreased cellular energy stores (decreased ATPase activity). Similarly, changes were observed in other nonspecific enzymes that led to a fall in acid phosphatase activity and a rise in alkaline phosphatase activity.

Forty-two patients with small cell lung cancer were treated with a combination of carboplatin, ifosfamide and etoposide. Vincristine was given on day 14 of each course, the courses being repeated every 28 days for a maximum of six. Thoracic radiotherapy was given 4 weeks after the last course of chemotherapy but no prophylactic cranial radiotherapy was administered. Thirty patients had clinically limited state disease, the remaining patients having contralateral neck lymphadenopathy and/or pleural effusions. Elevated enzyme levels (alkaline phosphatase, LDH, ALT, GGT) were noted in 69% of patients. Twenty-four patients (57%) achieved a complete response (CR) when assessed one month after the end of treatment. A further 21% of patients had a partial response (PR). Median duration of CR was 14 months and of PR 8 months. Cerebral metastases were the sole site of relapse in 13% of the CR patients. Myelosuppression was severe with a median nadir of neutropenia of 0.2 x 10(9) cells 1-1. However, 74% of the patient group received all six courses of chemotherapy and only 16 courses (7%) were delayed because of toxicity. There were three deaths associated with treatment-related neutropenia. The median survival of the total group was 14 months, with an actuarial 2 year survival of 37% and a minimum follow-up of 18 months. [A recent analysis, March 1989, demonstrated a 33%, 2 year actual survival.]

To establish the prevalence of liver enzyme alterations in the course of serious infections of diverse origin, 112 patients were studied retrospectively for the levels of GOT, GPT, LDH, GGT, alkaline phosphatase (FA) and bilirubin (BIL). Cases in which the values might be altered due to causes other than the infectious process were previously excluded. The prevalence of affectation of each of the parameters was the following: GGT, 39.1%; LDH, 33.3%; FAL, 30.1%; GOT, 29.5%; GPT, 24.8%; BIL, 18.3%. Seventy percent had at least one of these values changed. No significant differences were found in the incidence or intensity of the analytic alterations in function of the origin of the of infection, which suggests that these modification are nonspecific. Bilirubin levels were found to be significantly higher in the patients who died. On realizing the linear correlation analysis between the diverse parameters studied, a good correlation was found between them, suggesting a common pathogenetic mechanism.

Acute dehydration of diarrhoea of the breast-fed child is a type of hypovolemic shock which, by its severity and frequency is one of the major emergencies of pediatrics. The liver, as the site of many metabolic processes is mainly affected in the frame of the multiple-tissue involvement which is characteristic for this condition. The authors carried out a study of several enzymes (total LDH and the thermally-labile fraction, gluthamatdehydrogenase, gammaglutamyltranspeptidase, acid and alkaline phosphatase) in 27 breast-fed children. Determination of the enzymes was done on hospitalization, and 10 days later. The study showed that all the enzymes that were evaluated had moderate increases in 40.7-71% of all cases. The increases were significant (p less than 0.001). After 10 days the enzyme titers showed a tendency to become normal again, and slightly higher values were found in only 15-12% of all cases. Minimal hepatopathy can be considered, associated to the clinico-biological evolution of this severe conditions of the breast-fed child pathology.

1. Analysis of biochemical parameters were carried out on material pooled from 30 female sheep (Ovis aries ligeriensis). 2. The values determined were for the common metabolites and enzymes utilized for specific studies in general metabolism (urea, glucose, cholesterol, lipids, bilirubin, uric acid, creatinine, alkaline phosphatase, GOT, GPT, LDH, LAP, CGT, CK and amylase). 3. Results of these studies were compared with values from normal human adults. 4. The differences obtained in human and sheep ranges can be explained by the different physiology of the two species. 5. This study gives values for the sheep as an experimental animal in biomedical research.

1. Cefmenoxime (CMX) was administered with a dosage regimen of 20-25 mg/kg, 2-3 times daily (40-75 mg/kg/day) by intravenous drip over 30 minutes to 9 neonates with bacterial infections including purulent meningitis and septicemia. Clinical responses to the treatment were excellent in 7 and poor in 2. Bacteriological responses were "eradication of pathogens" from 8 of them except another patient with an infection due to Staphylococcus aureus. 2. Adverse reactions to CMX were observed in 6 of 18 neonates treated with the drug: diarrhea, oral thrush, and the elevation of S-GOT, S-GPT, LDH and alkaline phosphatase. None of the reactions, however, necessitated the discontinuation of the treatment. 3. Changes in blood concentrations of CMX in neonates with ages between 0 and 30 days were followed. These subjects included 16 mature neonates and 10 neonates with low birth weights. Intravenous drip infusion of 20 mg/kg of CMX over 30 minutes was immediately followed by peak blood CMX concentrations of 34.6-72.7 mcg/ml (mean +/- S.D.: 50.4 +/- 11.3 mcg/ml) in the mature neonates, and 22.3-78.2 mcg/ml (55.5 +/- 16.5 mcg/ml) in the neonates with low birth weight. Blood half-lives of the drug in the mature neonates were in the range from 1.7 to 20.7 hours (5.9 +/- 6.6 hours) in subjects with ages of 0-3 days, and 1.1-3.5 hours (2.0 +/- 0.8 hours) in subjects of 4-25 days. In neonates with low birth weight, they were 3.4-10.2 hours (7.2 +/- 2.7 hours) in subjects of 0-2 days, and 1.4-5.5 hours (3.0 +/- 1.5 hours) in subjects of 4-30 days. In other words, the blood half-lives of the drug tended to be longer in younger subjects. 4. Concentration of CMX in cerebrospinal fluid (CSF) were determined in a patient in acute stage with purulent meningitis caused by Mycoplasma hominis. Intravenous drip infusion of 80 mg/kg of CMX over 30 minutes was followed by CSF concentrations of 7.7-15.5 mcg/ml. 5. MICs of CMX for clinical isolates were determined. The drug was proved to have excellent antibacterial activities against Escherichia coli (3 strains) and group B hemolytic streptococci (2 strains) and these MICs were comparable to those of cefotaxime. The MIC of CMX for S. aureus (1 strain) was high at 25 mcg/ml with an inoculum size of 10(8) CFU/ml. This MIC value of CMX was higher than that of cefmetazole.
