Seasonal changes in the red blood cell indices in Arabian brood mares and their foals.

In 34 pure-bred Arabian horses, divided into four groups (Gr. I, 10 pregnant mares; Gr. II, seven barren mares; Gr. III, 10 foals born in 1981; Gr. IV, seven foals born in 1982), seasonal changes in haemoglobin level, haematocrit value, sedimentation rate, red blood cell number and diameter, percentage of erythroblasts and reticulocytes, and index F were studied. Seasonal cyclicity was found in all groups in the haemoglobin level, haematocrit value and RBC diameter. It was also found in the sedimentation rate (PCV) and in index F, but not for the youngest foals (Gr. IV). For the RBC number the cyclicity is given in both groups of foals, and the erythroblast and reticulocyte percentage only in the older foals (Gr. III). Out of eight indices studied cyclicity was found in all foals in Gr. III, in five of the mares in Groups I and II, and in four of the youngest foals in Gr. IV. There is no difference in the cyclicity of indices studied between pregnant and barren mares.

Diurnal changes in the hematological indices in the blood of racing Arabian horses.

In 8 stallions and 6 mares of pure Arabian horses the diurnal changes in the number and certain parameters of red and white blood cells were studied. All of them showed distinct diurnal changes but they did not fulfill the conditions of circadian rhythm according to Halberg. It was found that most of peaks occurred during the dark phase of 24 hr period except the percentage of eosinophils, erythrocyte diameters and cell rate sedimentation. The majority of indices studied showed the higher mean diurnal levels in the mares than in the stallions.

Seasonal changes in blood serum protein fractions and in activity of AspAT and AlAT in Arabian brood mares and their foals.

In 34 pure breed Arabian horses divided into four groups (Gr. I--10 pregnant mares, Gr. II--7 barren mares, Gr. III--10 foals born in 1981, Gr. IV--7 foals born in 1982) seasonal changes in total blood serum protein, its electrophoretic fractions and the activity of AspAT and AlAT were studied. Seasonal cyclicity was found in all groups in the amount of total serum proteins, and alpha 2- and beta 1-globulin fractions. Cyclicity was found in the level of albumin and activity of AspAT in three groups, not Gr. II, and in gamma-globulin, not Gr. IV. beta 2-globulin and AlAT cyclicity was found in two groups and alpha 1-globulin cyclicity was found only in Gr. II. Out of nine indices studied, cyclicity was found in eight of them in pregnant mares, Gr. I; in seven in older foals, Gr. III; in six in the young foals, Gr. IV; and in five in barren mares, Gr. II.

Seasonal changes in the white blood cell system, lyzozyme activity and cortisol level in Arabian brood mares and their foals.

In 34 pure-breed Arabian horses divided into four groups (Gr. I, ten pregnant mares; Gr. II, seven barren mares; Gr. III, ten foals born in 1981; Gr. IV, seven foals born in 1982) seasonal changes in the white blood cell system, cortisol level and lyzozyme activity were studied. Seasonal periodicity was found in all groups for the number of lymphocytes, segmented neutrophils and eosinophils and cortisol level. Leukocyte periodicity was found in three groups, but not in the barren mares. In lyzozyme activity there was periodicity in three groups but not in the youngest foals. In the stab neutrophils, basophils and monocytes no cycle was observed. The behaviour of the indices studied showed the influence of age of the horses (mature vs young) and the physiological state of the mares (pregnancy or barrenness).

The teratogenicity of hydantoins and barbiturates in humans, with considerations on the etiology of malformations and cerebral disturbances in the children of epileptic parents.

A total of 194 children of epileptic mothers and 71 children of epileptic fathers were examined for mental retardation, neurologic disturbances, major malformations, and acrofacial dysmorphias typical for hydantoin-barbiturate embryopathy (HB-E). HB-E was observed in nearly 7% of the children of mothers on anticonvulsants during pregnancy. Barbiturates and/or primidone were observed to induce the same dysmorphic features as hydantoins. The teratogenic potential of hydantoins may be slightly increased in combination with barbiturates/primidone. Neither the 71 children of epileptic fathers nor the 46 children of epileptic mothers without anticonvulsants exhibited symptoms of HB-E. The frequency of major, unspecific malformations was increased in children of epileptic mothers as well as in children of epileptic fathers as compared with the general population. Cerebral disturbances without dysmorphias were increased in children of mothers with and without anticonvulsants, but this was rarely the case in children of epileptic fathers. Cerebral disturbances were observed more often in children of mothers with seizures during pregnancy than in children of mothers without seizures. Multifactorial genetic influences on major malformations and influences of maternal seizures on cerebral disturbances in the offspring are likely.
