Critically ill or injured patients often have impaired cardiovascular function. Since low ionized calcium levels can cause such changes, serum calcium and urine calcium were measured in a prospective study involving 28 criticially ill or injured patients and 16 normal controls. Serum protein levels were also measured to calculate "corrected" total calcium levels. Ionized calcium levels are difficult to measure. Since ionic hypocalcemia is thought to increase the "nephrogenous production" of cyclic AMP, cyclic AMP levels were measured in the blood and urine of these patients and the "nephrogenous" cyclic AMP calculated from the creatinine clearance. The mean total serum calcium in these patients was 7.7 +/- 0.8 mg/dl (S.D.). This was significantly lower (p less than 0.001) than our controls (9.6 +/- 0.6). When corrected for hypoproteinemia, the mean serum calcium (8.7 +/- 0.8) was still significantly lower (p less than 0.005) than control (9.4 +/- 0.5). The mean urine calcium excretion in the patients (56 +/- 66 mg/100 ml G.F.R.) was lower, but not significantly so, than in the controls (84 +/- 44 mg/100 ml G.F.R.). The "apparent nephrogenous" cyclic AMP in the study group was 2,731 +/1 1,451 pm/ml/100 ml G.F.R. The nephrogenous cyclic AMP had a negative correlation (r =-0.45) with "corrected" total calcium levels. Thus "total," "corrected" total, and "ionized" calcium levels appear to be reduced in the majority of critically ill or injured patients studied. The clinical implications of these findings and the potential value of serial cyclic AMP determinations in blood and urine will be discussed.

Oak poisoning occurred in crossbred cattle due to eating immature tender oak (Quercus incana) leaves. Mortality was 70%. The animals exhibited anorexia, severe constipation and brisket edema. The feces were hard, pelleted and coated with blood and mucous. Significant reductions in blood hemoglobin and mean corpuscular hemoglobin, and significant elevations in serum bilirubin were observed. Serum urea nitrogen and creatinine were greatly increased. There was bilirubinuria, proteinuria, hypoproteinemia and hypocalcemia, and greatly increased activities of serum aspartate aminotransferase, lactate dehydrogenase and alkaline phosphatase. The levels of tannins and condensed tannins were 97.7 mg tannic acid equivalent and 5.8 mg catechin equivalent/g of dry leaves. There was extensive nephro- and hepatotoxicity in the affected cattle due to hydrolysable tannins and simple phenols in the oak leaves.

We evaluated diagnostic utility of the hematological, biochemical and serological tests comprised in the "essential laboratory tests" advocated by the Japan Society of Clinical Pathology in 1,026 new patients visiting the outpatient unit of Comprehensive Medicine, National Defense Medical College. Of 750 evaluable patients, 52 showed anemia associated with such conditions as ulcer or cancer of digestive tract, inflammatory disease, or renal failure. Leukocytosis (greater than 9,000/microliters) was found only in 25 of 112 CRP-positive (greater than 0.3 mg/dl) patients, suggesting bacterial infection. Forty-four patients showed hypoproteinemia and/or hypoalbuminemia indicating chronic conditions including liver and inflammatory disease. Elevation of serum creatinine level was found in 4 patients subsequently diagnosed with renal failure, whereas 32 patients demonstrated elevated BUN. After application of the "essential laboratory tests", 97 patients were diagnosed with hyperlipidemia (total cholesterol greater than 230 mg/dl and/or triglyceride greater than 250 mg/dl). Determination of serum enzyme activity was useful not only for the diagnosis of liver dysfunction or biliary tract disease but also for those of hematological malignancies or myogenic disorders; however, in patients with abnormal values of LDH, gamma-GT and ALP, clinical significance was not clarified in 53%, 38% and 59%, respectively. These results indicate that the "essential laboratory tests" are useful in the following aspects of primary care medicine: for (1) estimation of the degree or nature of infection or inflammatory status; (2) classification of anemia and its relation to underlying diseases; (3) evaluation of patient general condition and protein-producible function of liver; (4) evaluation of renal function; (5) ambulatory screening for metabolic diseases such as hyperlipidemia; and (6) diagnosis of liver and biliary tract diseases.

High dietary protein intake, in the past recommended for nephrotic syndrome, does not improve hypoproteinemia and may accelerate progressive renal damage. In contrast, low-protein diets reduce proteinuria and preserve renal function in experimental renal models of nephrotic syndrome. In this study, 20 steroid-resistant, nephrotic patients were treated with a pure vegetarian, low-protein diet, supplemented with essential amino acids and ketoanalogues (supplemented vegan diet, SVD) for 4.6 +/- 3.1 months. Before the study, these patients followed an unrestricted protein, low-sodium diet (LSD). Proteinuria, daily urea nitrogen excretion and creatinine clearance decreased significantly on SVD. A similar lowering effect of SVD was observed on serum total cholesterol. Seven of the 20 patients changed from LSD to SVD and vice-versa on 3 occasions, and in all cases, we found an increase of proteinuria during the LSD period. Serum albumin, HDL cholesterol, triglycerides and anthropometric measurements did not change on SVD. Our data suggest that SVD exerts a favorable effect on proteinuria and hypercholesterolemia in nephrotic patients, without inducing clinical or laboratory signs of malnutrition.

The dose dependency of germanium dioxide(GeO2)-induced nephrotoxicity was investigated experimentally in rat groups orally treated with high (150 mg/kg/day), moderate (75 mg/kg/day), or low (37.5 mg/kg/day) doses of GeO2, and in an untreated group. Renal dysfunction, indicated by the increase of blood urea nitrogen and the decrease of creatinine clearance, and systemic toxicity by weight loss, anemia, and hypoproteinemia were more apparent in rats treated with higher dose of GeO2. Urinalysis including daily urinary protein excretion did not reveal any abnormalities in any of the groups. Urinary excretion and renal-tissue content of Ge were significantly elevated in the group of the higher dose of GeO2. Light microscopically, vacuolar degeneration and depositions of granules positive for periodic acid-Schiff in distal tubules were predominant in the higher-dose group of GeO2. The present study demonstrates that GeO2-induced nephrotoxicity develops dose dependently.

Clinico-pathological studies were made on rats with polycystic kidney disease (PCK), a congenital renal disorder transmitted as an autosomal recessive trait and characterised by facial and skeletal anomalies, with the results summarised as follows: 1) Affected animals had a poor weight gain and slightly increased urinary excretion of low molecular weight protein from 2 months after birth, and developed polyuria and hypocalciuria 5 months postnatally. They had elevation of serum urea nitrogen, increased urinary excretion of urea nitrogen and hypoproteinemia 8 months postnatally though without showing elevated serum creatinine and died around 10 months of life. 2) Kidneys of chin rats appear granular in surface, enlarge little by little while preserving the entire kidney morphology; a small cyst is formed in the renal medulla 2 months postnatally, then enlarges gradually to encroach upon the cortex and grows to involve all cortical layers by 8 months of life. This cyst was revealed by lectin staining to be derived from the collecting ducts and was assumed to correspond, both morphologically and clinically, to the infantile or juvenile form of PCK in humans. Pathogenetic factors of the characteristic facies and skeletal abnormalities were also investigated.

In this problem-oriented review of abnormalities associated with cancer, we have emphasized distinctive diagnostic points related to pathogenesis for each condition and outlined how the approach to management is determined by pathogenesis. For abnormalities of the complete blood count, it is important to distinguish between abnormalities directly related to marrow malignancy and abnormalities associated with extramarrow malignancy. Hemopoietic tumors consist of developmentally deficient blood cells produced by a clonal population of malignant stem cells. Tumors infiltrating marrow cause overcrowding in the limited marrow microenviroment. Extramarrow malignancies cause blood abnormalities, but the potential for normal marrow function is present. Abnormalities of blood cells secondary to therapy are usually clearly identified by consideration of clinical history. The initial differential diagnosis for hypercalcemia is malignancy. An aggressive diagnostic approach may be needed to identify the neoplasm, and therapy should incorporate measures to prevent renal failure. Hypoproteinemia and hyperproteinemia may be caused by neoplasia. Monoclonal gammopathies should be identified and may be associated with hyperviscosity syndrome. Hypoglycemia in the adult animal is most frequently caused by insulin-secreting tumors, but it has also been associated with hepatic and other tumors. Increased blood urea nitrogen, creatinine, lipase, amylase, and liver enzyme activities may also be caused by malignancy. Inadequate urine concentrating ability may be caused by hypercalcemia or malignancy-associated renal insufficiency. Hematuria in older animals is suggestive of urinary tract neoplasia. Exfoliated tumor cells may be identified in the urine sediment of these patients.

The pathophysiology of the nephrotic syndrome (NS), characterized by protenuria, edema, sodium retention and hyperlipidemia, is not clear. We studied the role of some systemic factors on sodium retention in an experimental model of NS. NS was induced in rats by a single subcutaneous injection of puromycin aminonucleoside (PA) (15 mg/100 g); control animals received vehicle. All rats were kept in metabolic cages for 24 days (3 days before and 21 days after PA-injection). Urine was collected daily. Blood samples were obtained every day until day 10, and then every other day up to the end of the study. The rats showed the following alterations after PA injection: a) a rise in serum angiotensin converting enzyme activity (ACEA) and plasma aldosterone (PAldo) at day 1; b) a rise in urinary aldosterone (UAaldoV), azotemia and sodium retention at day 2; c) massive proteinuria (UProt) and decrease in plasma angiotensinogen concentration (PAC) at day 4; d) increases in plasma renin activity (PRA), plasma renin concentration (PRC) and serum creatinine as well as hypoproteinemia, hypercholesterolemia, hypertriglyceridemia, ascitis and edema at day 5; e) increase in urine volume at day 6. PAldo became normal at day 7; urine sodium (UNaV), PRA and PRC at day 8; UAldoV at day 9; serum urea and ACEA at day 10; urinary volume at day 11; PAC, serum total protein and creatinine at day 12. The edema disappeared at day 11. UProt, hypercholesterolemia and hypertriglyceridemia persisted, though they decreased substantially by the end of the study (day 21). Light microscopy studies revealed normal glomerular morphology, but electron microscopy showed fusion of podocytes before proteinuria. These data suggest that: a) sodium retention was not a consequence of proteinuria or hypoproteinemia; b) sodium retention seems non-related to renin secretion, but may be partially mediated by a fall in glomerular filtration rate or by an increased tubular resabsorption secondary to other factors; c) the increase in PAldo, UAldoV and ACEA are non-related to renin secretion: all occurred before PRA rose; d) water retention, increase in PRA and PRC, hypercholesterolemia and hypertriglyceridemia are secondary to the hypoproteinemia.

Germanium (Ge; atomic number 32, atomic weight 72.6) belongs to IVb group of the Periodic Table and is found as a trace metal in soil, rocks, plants, and animals. It is widely used in industry because of its semiconductive nature. Some biological activities have been shown in Ge derivatives. Recently, patients with persistent renal damage after chronic ingestion of germanium dioxide (GeO2)-containing compounds have been reported in Japan. This study aimed to investigate subacute nephrotoxicity of GeO2 in Lewis male rats. The rats were treated orally with GeO2 for 13 weeks (GeO2 group) and were compared with those treated with GeO2 for only the first 4 weeks (GeO2-4-week group) and with untreated controls. Renal dysfunction was demonstrated by the increased serum creatinine, BUN, and serum phosphate and decreased creatinine clearance. Liver dysfunction was observed as demonstrated by the increased GOT and GPT, and hypoproteinemia by the decreased total protein and albumin in the GeO2 group. However, daily urinary protein excretion or urinalysis did not differ among the groups. Kidney weight and Ge content of tissues were significantly elevated in the GeO2 group. With the light microscope, vacuoles and the depositions of PAS-stained particles, which correspond to electron-microscopic dense granules in the swollen mitochondria, were predominantly observed in distal tubular epithelium in the GeO2 group. Even in the GeO2-4-week group of rats, serum creatinine was increased and the above-mentioned histological abnormalities were observed, but were less intense.

Bilateral renal dysplasia and nephron hypoplasia was diagnosed in a Quarter Horse foal with clinical signs of lethargy, convulsions, and diarrhea. Laboratory evaluation revealed anemia, hypoproteinemia, leukopenia, hyponatremia, hypochloremia, and hyposmolality. The foal also had high concentrations of serum creatinine, BUN, and phosphorus. Evaluation of urinary indices revealed a high ratio of urinary gamma-glutamyl-transferase activity to concentration of creatinine, as well as a high fractional clearance ratio of sodium and potassium. Intravenous treatment with saline solution (0.9% NaCl) and antimicrobials provided only temporary resolution of some of the abnormalities. Diagnosis was partly established by histologic evaluation of renal tissue obtained via an ultrasonographically guided biopsy and was confirmed at necropsy. Pathologic changes in the kidney were unique in that the size of the kidneys, along with the appearance and number of glomeruli, were essentially normal despite marked hypoplasia of nephron tubules in the medulla.
