Adjuvant post-operative chemotherapy in bitches with mammary cancer.

The survival time in a group of eight bitches with malignant mammary tumours given adjuvant post-operative chemotherapy was compared with survival in another group of eight bitches with mammary cancer which were treated by surgical excision alone. The same surgical procedure was used in both groups. All bitches had stage III disease according to the World Health Organization clinical staging system. Histologically, 10 of the bitches had complex carcinomas (carcinomatous mixed tumours), the remaining six bitches had carcinosarcomas. The chemotherapeutic protocol used was a combination of 5-fluorouracil (150 mg/m2 of body surface area) and cyclophosphamide (100 mg/m2) given on the same day, intravenously, every week for four consecutive weeks. Chemotherapy was started one week post-surgery. Selected haematological parameters (packed cell volume, white blood cell count, platelet count and differential white blood cell count) and serum biochemical parameters (alanine aminotransferase, alkaline phosphatase, blood urea nitrogen and creatinine) were measured before and during chemotherapy. Survival analysis indicated that the chemotherapeutic regimen had a positive influence on the disease-free interval and the survival time of the eight bitches (P < 0.05). Although leucocyte numbers were significantly decreased (P < 0.001) during chemotherapy, the mean leucocyte counts remained within normal limits. Temporary leukopenia was noted only in one bitch. Packed cell volume and alkaline phosphatase increased significantly (P < 0.05) but within normal limits. Creatinine was also increased significantly (P < 0.01) but the mean creatinine concentrations were within normal limits, although in half of the bitches the concentrations occasionally rose above normal.

The Preterm Prediction Study: the value of serum alkaline phosphatase, alpha-fetoprotein, plasma corticotropin-releasing hormone, and other serum markers for the prediction of spontaneous preterm birth.

OBJECTIVE: High levels of a number of analytes are found in maternal blood; alkaline phosphatase,alpha-fetoprotein, and corticotropin-releasing hormone have been associated with spontaneous preterm birth. We investigated the relationship between 8 potential blood markers and subsequent spontaneous preterm birth in asymptomatic pregnant women. STUDY DESIGN: We performed a nested case control study that involved 127 women who were enrolled in the preterm prediction study and who had a singleton spontaneous preterm birth at <35 weeks and 127 women who had a term birth and served as matched (age, parity, center) controls. Serum that was collected at 24 and 28 weeks was analyzed for alkaline phosphatase, alpha-fetoprotein, corticotropin-releasing hormone, and 5 other analytes. RESULTS: Alkaline phosphatase, alpha-fetoprotein, and corticotropin-releasing hormone, but not other analytes, were significantly elevated in pregnancies that ended in spontaneous preterm birth. For alkaline phosphatase at 24 weeks, the odds ratio for spontaneous preterm birth at <32 weeks was 6.8 (range, 1.4-32.8) and for spontaneous preterm birth at <35 weeks 5.1 (range, 1.7-15.6). Similar results were found at 28 weeks. For alpha-fetoprotein at 24 weeks, the odds ratio for spontaneous preterm birth at <32 weeks was 8.3 (range,2.2-30.9) and for spontaneous preterm birth at <35 weeks was 3.5 (range, 1.8-6.7). The levels at 28 weeks were still predictive but less so than at 24 weeks. Corticotropin-releasing hormone, at 28 weeks but not at 24 weeks, was predictive for spontaneous preterm birth at <35 weeks, with an odds ratio 3.4 (range, 1.0-10.9). CONCLUSION: Elevated alkaline phosphatase and alpha-fetoprotein are associated with subsequent spontaneous preterm birth in asymptomatic pregnant women at 24 and 28 weeks. Elevated corticotropin-releasing hormone levels at 28 weeks are associated with spontaneous preterm birth at <35 weeks.

Effect of magnesium deficiency on vitamin B2 and B6 status in the rat.

OBJECTIVE: The present study was undertaken to investigate the effect of dietary magnesium (Mg) deficiency on vitamin B2 (riboflavin) and B6 (pyridoxine) status in rats. METHODS: We fed Wistar rats an Mg-deficient diet (56 mg magnesium per kg food) for 70 days. On days 21, 35 and 70 we measured Mg and manganese (Mn) in plasma and whole blood, alkaline phosphatase in plasma, erythrocyte glutathione reductase activity coefficient (AC-EGR) for riboflavin status, and erythrocyte aspartase transaminase activity coefficient (AC-EAST) for vitamin B6 status. RESULTS: Intake of the Mg-deficient diet significantly decreased plasma and whole blood levels of Mg and plasma alkaline phosphatase activity on all sampling days. The Mg deficit had no effect on plasma concentrations of Mn, but significantly increased whole blood levels of this element on days 35 and 70. The Mg-deficient diet had no effect on AC-EGR, and thus appeared not to affect riboflavin status. However, AC-EAST was significantly increased on day 70, implying that the animals were at risk for vitamin B6 deficiency. CONCLUSION: Mg deficiency impairs vitamin B6 status by depleting intracellular Mg and thus inhibits the activity of alkaline phosphatase, a metalloenzyme required for the uptake of pyridoxal phosphate by tissues. Although part of the intraerythrocyte loss of Mg is countervailed by Mn, which can act as a substitute activator of alkaline phosphatase, the degree of compensation is insufficient to fully offset the decrease in activity caused by Mg depletion.
