Mathematical Correlation

Determinations of calcium, inorganic phosphorus, cholesterol and lipoid phosphorus were made on a series of animals recently received from the dealer for the purpose of determining the trends of these 4 blood constituents throughout the year with the degree of their respective variations and mathematical correlation. It was found that for the 80 animals examined, calcium varied from 14.5 ±0.10 to 18.5 ±0.39 mg. and inorganic phosphorus 4.960 ±0.20 to 6.820 ±0.20 mg. per 100 cc. of blood serum. Cholesterol varied from 51.1 ±1.18 to 73.3 ±1.34 mg. and lecithin from 94.8 ±1.397 to 168.3 ±10.18 mg. per 100 cc. of whole blood. Of the 6 possible combinations in calculating the coefficient of correlation for the trend throughout the experiment, 3 stand out as of mathematical significance, namely the following. Between inorganic phosphorus and lecithin the coefficient of correlation was found to be –0.794 ±0.088; between calcium and cholesterol –0.887 ±0.051 and between cholesterol and lecithin +0.560 ±0.164.

The Mean

A series of determinations of inorganic phosphorus, calcium, cholesterol, and lecithin were made on a group of 10 animals living in the laboratory from Oct. 27, 1927, to May 17, 1928. A marked difference in both the trend and absolute values was noted in animals living in the laboratory when compared with the values obtained for animals living out-of-doors. With animals living in the open, the trend of variation for calcium was found to be the same. However, animals living in the laboratory maintained a higher level over the same period of time. The inorganic phosphorus and lecithin both showed a marked decrease and both maintained a lower level than was found in animals just received from the dealer. The cholesterol content of whole blood exhibited a similar trend in both groups of animals. However, it was found that animals living in the laboratory maintained a lower level than animals living out-of-doors. The mean value for calcium was found to be 15.7 ±0.05, for inorganic phosphorus 4.65 ±0.05 mg. per 100 cc. of blood serum, and for cholesterol 58.2 ±0.39 and lecithin 118.4 ±1.13 mg. per 100 cc. of whole blood. The coefficients of correlation having the highest degree of mathematical significance were obtained from the mean values for individual animals.

Experiments are reported in which it was shown that the calcium, inorganic phosphorus, cholesterol, and lecithin in the blood of normal rabbits were influenced by inoculation with a malignant tumor (4). Animals in which death was due to tumor gave results on which the following conclusions are based: 1. A marked increase in inorganic phosphorus of blood serum and cholesterol of whole blood followed inoculation. 2. The ratios of cholesterol to calcium and lecithin to calcium increased in trend, while the calcium to inorganic phosphorus, lecithin to cholesterol, and lecithin to inorganic phosphorus ratios showed a marked decrease in trend. 3. The r cholesterol-lecithin were all negative.

Antiheparin Activity

SummaryThe antiheparin activity of normal serum has been studied by comparing the antiheparin activities of sera obtained from normal whole blood, platelet-rich plasma and platelet-’free’ plasma with a purified platelet extract during differential isoelectric precipitation and by gel filtration chromatography.The mean values for the activity of PRP-serum and PFP-serum were 106% (S.D. 11) and 10% (S.D. 3) of untreated whole blood respectively. The activity of whole blood serum, PRP serum and whole blood serum plus platelet extract precipitated under identical physical conditions, i.e. pH 7.0, I =0.008, indicating that the activities of the three samples are probably associated with PF4. PF4 precipitated from human platelet extract at pH 4.0, but this is probably due to the difference in the two biochemical environments investigated, i.e. serum and platelet extract.The gel filtration experiments revealed striking similarities between the major antiheparin activities of serum and platelet extract. At physiological pH and ionic strength both activities were associated with high molecular weight material, but at physiological pH and elevated ionic strength both activities behaved as much smaller entities of molecular weight between 25,000 and 30,000 daltons and it seems very likely that both activities are associated with the same molecule, i.e. PF4.

The article is devoted to the solution of an urgent problem- influence of different lighting modes on the dairy productivity of cows. 2 groups of cows with 20 heads each were formed. In control group, light in the cowshed was 50-75 Lux for a light period of 7.5 h in January to 16.5 h in June, and in experimental group - 150-200 Lux and 16 h, respectively. It was found that the intensity and duration of illumination affects physiological state, reproductive ability and milk productivity of cows. In the experimental group of cows, compared with the control group, hemoglobin content in blood increased by 4.6% (P < 0.01), red blood cells - by 20.6% (P < 0.05), total protein - by 11.2% (P < 0.001), glucose - by 39.1% (P < 0.05). There was a tendency to increase the total calcium and inorganic phosphorus in blood serum of cows of the experimental group. The level of alkaline phosphatase in blood serum of cows in the control group was 71.5% (P < 0.01) higher than that of cows in the experimental group. Milk yield per 1 cow in the experimental cowshed was 433 kg more than in the control. The cost of 1 kg of milk in the experimental group was 0.94 rubles lower, and the profitability of milk production and sales is 9.42% higher than in the control group. To increase the milk productivity of cows, it is recommended to increase light level in barns for tethered keeping to 150-200 Lux, with the duration of lighting in the winter and transition periods of year up to 16 hours per day.

Karakachan sheep represents an endangered, indigenous sheep breed from Balkan Peninsula. There is relatively little information about the characteristics of this sheep breed in the veterinary scientific literature. The aim of this research was an examination of certain metabolic profile parameters of the Karakachan sheep blood serum, and variability of their concentrations in comparison to age and some other indigenous sheep breeds from Balkans. Examination was conducted on 14 clinically healthy sheep divided in two age groups. Blood samples were collected by puncture of v. jugularis and blood serum was separated after spontaneous coagulation. The concentrations of total protein, albumin, calcium, inorganic phosphorus, aspartate amino transferase (AST) and ?- glutamyl transferase (GGT) were determined. In relation to age of Karakachan sheep, statistically significant difference between the calculated mean values of examined parameters was not observed. A statistically significant difference was found between the mean concentrations of the studied parameters in Karakachan sheep and other breeds in total protein (Tsigai, Dubrovnik and Dalmatian sheep), albumin (Dalmatian), calcium and inorganic phosphorus (Tsigai, Dubrovnik) and AST's (Dalmatian, Karakachan sheep from Bulgaria).
