Many normal cerebrospinal fluids contain an alkaline (pH 9.8) and an acid (pH 4.9) phosphatase. Both the alkaline and the acid phosphatase were significantly increased in the spinal fluids from patients with meningitis or poliomyelitis, but not in the fluids from patients with syphilis. The alkaline phosphatase activity was correlated with both the concentration of protein in the spinal fluid and with the white cell count, whereas the acid phosphatase was correlated with neither. When correction was made for the significant correlation between cell count and protein concentration, the partial correlation between alkaline phosphatase activity and both protein concentration and cell count remained significant statistically. In pathological conditions it appears likely that the alkaline phosphatase is derived partly from the polymorphonuclear leucocytes in the fluid and partly from the blood plasma. The acid phosphatase is probably derived from the lymphocytes of the fluid and possibly also from the blood plasma. It is unlikely that either of these enzymes comes from the substance of the brain or spinal cord. Acid phosphatase would be of more value than alkaline phosphatase as a diagnostic aid, since normal fluids contain much less of this enzyme.

Abstract A new substrate, ammonium thymolphthalein monophosphate, is proposed for use in alkaline and acid phosphatase determinations. The ammonium salt shares the advantages of the sodium salt, but is a more stable substrate and results in more stable working reagents. The substrate is buffered at pH 10.1 in diethanolamine for determining alkaline phosphatase activity in 5 min, and at pH 5.9 in citrate buffer for determining acid phosphatase activity in 30 min. The substrate is relatively specific for bone and liver alkaline phosphatase and prostatic acid phosphatase. Coefficients of variation were 2.5% and 6.6% for alkaline and acid phosphatase, respectively.

ABSTRACT In both young and old laying hens the protein-bound calcium fraction in blood plasma decreased following feed supplementation of 0.05% thyroprotein, whereas the plasma alkaline phosphatase activity significantly increased. The enzyme response was found to be delayed in old as compared to young hens, significantly higher absolute levels being found in the latter. Propylthiouracil treatment caused a marked decrease in protein-bound calcium levels and alkaline phosphatase activity in both young and old hens. The uterine calcium levels and alkaline phosphatase activity in the thyroprotein treated birds did not show any significant differences as compared to the controls, except in the group of old hens receiving the highest dose, in which the calcium level was significantly decreased and the enzyme activity significantly increased. Both propylthiouracil treated groups showed a significant decrease in uterine calcium and alkaline phosphatase activity.

ABSTRACT Objectives: To investigate the relationship between salivary alkaline phosphatase activity (ALP), protein concentration, and chronological age with cervical vertebral maturation stages (CVMS) as noninvasive biomarkers for skeletal maturity assessment. Materials and Methods: This cross-sectional study included 79 subjects (48 females, 31 males; 7 to 23 years old) categorized into five CVMS based on lateral cephalographs evaluated by three examiners. ALP activity and protein concentration in unstimulated whole saliva were compared among five CVMS. The association between age and CVMS was assessed and five multinomial logistic regression models were utilized to predict CVMS based on salivary ALP activity, protein concentration, and chronological age. Results: Salivary ALP reached the peak at early pubertal stage and then declined with a significant difference between CVMS I and CVMS II (P < .001) and between CVMS I and CVMS V (P = .004). A significant positive correlation between age and CVMS was found (rs = 0.763, P < .001). The models' overall correct classification rates for predicting CVMS were 32.9% using protein concentration, 35.4% using ALP activity, and 53.2% using both ALP activity and age. Conclusions: The combination of salivary ALP activity and chronological age may provide the best CVMS prediction.

Abstract 1. The acid and alkaline phosphatase activity has been determined on a series of suspensions of white cells obtained from both man and the rabbit by several different methods. 2. A statistical analysis of the results shows that for both species the alkaline phosphatase of white cell suspensions is confined chiefly to the polymorphonuclear leukocyte and the acid phosphatase is chiefly in the lymphocyte, although the polymonphonuclear leukocyte contains lesser concentrations of this enzyme also. 3. Although this qualitative distribution was the same for both species studied, quantitatively the rabbit differed from man. The activity of the alkaline phosphatase of the rabbit polymorphonuclear leukocyte was eight times that of the corresponding human cell, while the activity of the acid phosphatase of the human lymphocyte was more than twice that of rabbit lymphocyte.

AbstractThe acid and alkaline phosphatase activity was measured in the developing egg and in the alimentary canal of aging nymphs as well as adult males and females of different ages. Para-nitrophenol was used as colorimetric standard and disodium p-nitrophenyl phosphate as substrate. Activity was measured in terms of micromoles of p-nitrophenol liberated from the substrate as a result of enzyme action.Acid phosphatase activity was noticed to increase with the embryonic development and was higher than in the case of alkaline phosphatase. The alkaline phosphatase activity was lowest in the freshly laid egg, but increased more sharply than acid phosphatase during embryonic development.The activity of both the acid and alkaline phosphatases was highest in the first instar and declined gradually to the fifth instar. The activity of acid phosphatase was higher than alkaline phosphatase in all stages except the first instar where it was almost equal. The activity of both the enzymes was higher during the intermoulting period and declined at each moult indicating a hormone–enzyme relationship.In adults, activity of both the enzymes increased up to the maturation period after which the activity gradually decreased. Acid phosphatase activity was generally higher in males whereas alkaline phosphatase activity was generally higher in females. In almost all cases, the acid phosphatase activity was found to be higher than the alkaline phosphatase.

Evidence has been obtained for acid phosphatase activity (on p-nitrophenyl phosphate as substrate) at pH 4.8 in cell-free extracts of Phaeodactylum tricornutum, Skeletonema costatum, Cyclotella nana, Monochrysis lutheri, Isochrysis galbana, and Dunaliella tertiolecta grown photo-autotrophically in pure culture. No alkaline phosphatase activity at pH 10.5 was observed.

Intramarsupial glochidia of Anodonta anatina (L.) and Pseudanodonta complanata (Rossmässler) were studied in southern Finland. Material staining positively with periodic acid – Schiff's reagent (PAS), neutral lipid reserves, and acid phosphatase activity have different distributions in the mantle of the two species. Moreover, the mucous covering of the mantle of the two glochidia behaves differently on critical-point drying. The presence of microvilli with alkaline phosphatase activity on the mantle surface and acid phosphatase activity in the mantle cells in both glochidia suggest that the mantle plays a role in nutrient uptake and digestion and possibly also in electrolyte uptake. The primordia of the stomach, digestive diverticula, and intestine, at least in A. anatina glochidia, contain neutral lipids and exhibit acid phosphatase activity: In A. anatina glochidia, a microvillous layer with alkaline phosphatase activity continues from the ventral walls of the lateral pits to the suspected kidney diverticula. In both glochidia, there may be three pairs of rudimentary ganglia, which do not stain with methylene blue. The eight ciliated sense organs of the glochidia are methylene blue- and PAS-positive and they exhibit succinate dehydrogenase and acid phosphatase activity. In each mantle lobe, the enveloping cell of the dorsal ciliary organ is interconnected with those of the ventral triad via a cellular fold or "tract," and the ciliated central cells of the organs send axons towards each other.
