Abstract By using of the double antibody sandwich method of ELISA, the activities of five cytokines including IL-2, IL-4, IFN-α, IFN-β and TNF-α from the blood serum, liver, intestine and spleen at two developmental stages of Chinese giant salamander (Andrias davidianus) were determined to analyze the distribution of the cytokines. The result indicated that five cytokines were found in these four tissues, while their activities were different in different tissues and different ages. The highest activity of IL-2 and IL-4 was all present in blood serum of two different ages. The activity of IFN-α was the highest in blood serum of 1-year-old and in spleen of 2-year-old, respectively. The activity of IFN-β was also highest in blood serum of two different ages. The activity of TNF-α was highest in liver of two different ages. Thus, this study provides convincing reference for blood serum and liver as the most important distribution area of Chinese giant salamander.

This paper focuses on the geographical distribution and the habitats of Lymnaea natalensis, the snail intermediate host of the liver fluke, Fasciola gigantica, as reflected by the collection sites of its 4 552 samples currently on record in the National Freshwater Snail Collection (NFSC) of South Africa. Although this species was represented in a variety of waterbodies, the majority of samples(±70%)came from rivers, brooks and dams and in 70.8% of the cases the water was described as permanent and in 71.8% as slow flowing or standing. The results of life-table studies conducted by various authors indicated that temperature should be a relatively unimportant factor in determining its geographical distribution, but that the availability of permanent water should be decisive for its presence in a given habitat. These results are in agreement with the finding that only 7.5% of the samples of this species in the NFSC were collected in habitats which were described as seasonal. Furthermore, it gives a logical explanation for the sporadic occurrence, or total absence of this species in the more arid regions of South Africa. Water impoundments and irrigation networks contribute to a large extent towards creating perennial habitats which would be suitable for L. natalensis. As intermediate host for one of the liver fluke species which already is an economic factor in South Africa, this certainly is an aspect which ought to be reckoned within the planning and construction of new irrigation schemes.

Variable Factor

The results of the foregoing experiments may be briefly summarized as follows: The amount of antitoxic substance obtained by precipitation with magnesium sulphate from the blood-serum of the horse corresponds, as nearly as can be determined by the use of test guinea-pigs, in full to the protective power of the serum from which it is obtained, i. e. the precipitate from 1 cc. of serum will protect against the same amount of toxin as 1 cc. of the serum itself. Equal amounts of the precipitates by magnesium sulphate from immunized and non-immunized horses act differently toward toxin; i. e. the proportion of protective substance to the precipitate from non-immunized serum is exceedingly small as compared with the proportion of antitoxin to the precipitate from sera of immunized horses. The average precipitate from the sera of immunized horses, as obtained by magnesium sulphate, is more abundant than the average precipitate from sera of non-immunized horses. In the case of the same animal before and after immunization, the serum before immunization gives a less abundant precipitate with magnesium sulphate than the serum tested after immunization. The proportion of increase per unit of antitoxic strength for the same or different horses is not constant. This may be due to an increase of inactive substances (in their relation to diphtheric toxin) or to imperfect methods of determination. The precipitates obtained by magnesium sulphate give all the reactions recognized as characteristic of globulins, and as distinguishing them from other albuminous bodies. We are not warranted, then, in the present state of our knowledge, in considering any part of these precipitates as other than globulin. But it does seem warrantable to conclude, from the fact that the globulins of normal serum do not protect, or only in comparatively large amounts, against diphtheric toxin, that new globulins are formed, or rather greatly increased in the serum of immunized horses, and that these globulins protect against the toxin. These increased globulins and the inert globulins (which from obvious causes are a very variable factor) are both precipitated by magnesium sulphate. Every animal has a physiological and pathological history more or less widely diverging from the normal, hence absolute conformity in the results obtained is not to be expected, at least with our present methods of differentiation.

Abstract The aim of the presented study was the estimation of optimal Ca and P levels applied before calving together with anionic salt addition, as an element of hypocalcaemia and hypophosphataemia prevention. The experiment was carried out during the dry period on 48 cows with similar milk yield in the previous lactation. Cows were divided into four groups. In group I (control) the amount of minerals was in accordance to NRC standards. In experimental groups (groups II-IV), two weeks before calving, cows received 140 g/day/head of hydrated magnesium sulphate to achieve dietary cation- anion difference at the level of about 50 mEq/kg DM. In groups II and III cows received calcium carbonate (100 g/day) 10 days a.p. (antepartum) (group II), or 5 days a.p. (group III), while cows in IV group received dicalcium phosphate (100 g/day) for 5 days a.p. Application of MgSO4 × 7H2O significantly affected the urine pH of cows from group III and IV 4-5 d. before calving - 6.45 and 6.81, respectively. The acidification of urine was observed after calving in group IV (7.13). In cows from group II (100 CaCO3 10 days a.p.) urine pH decline was not found (7.97-7.75). In that group the incidences of hypophosphatemia were noted (blood serum inorganic P level 1.41-1.46 mmol/l). Addition of magnesium sulphate prevented hypocalcaemia occurrence - 4-5 d. before calving the concentration of ionized Ca in blood serum was 1.11, 1.13 and 1.16 mmol/l (respectively for group II, III and IV). Reproductive functions were significantly improved after the application of CaCO3 and CaHPO4 for 5 days a.p. in comparison with control and group II - progesterone concentration in the blood serum on the 45th day of lactation was 1.396 - 1.409 vs 0.799 - 0.401. The correlation between progesterone and inorganic P level in serum was almost significant. Based on the obtained results a treatment optimal in prevention of hypocalcaemia and hypophosphataemia is the application of 50 g CaCO3 and 50 g of CaHPO4 for the last 5 days of the dry period together with MgSO4 × 7H2O given for 14 days a.p.

Liver Flukes

Gall bladders from 80 mature cattle infested with liver flukes were shrunken; their walls were thickened; and mucosa was raised into rugose folds, nodules and papillary projections. All contained thick bile and mature liver flukes, predominantly Fasciola gigantica and to a lesser extent Fasciola hepatica. There was an adenomatous proliferation of the lining epithelium as well as of submucosal glands forming numerous tubuloalveolar structures and cysts lined with a uniform layer of columnar epithelium. Fibrous stroma was more than normal, and there was a mild to heavy infiltration by inflammatory cells. Some bladders had many enterochromaffin cells in the epithelium lining the glandular structures. Mitotic figures were rare, and there was no evidence of malignancy. The condition is inflammatory and hyperplastic and is believed to be common in cattle infested with liver fluke. The clinical effects of this condition have not been studied.
