DEVELOPMENT
OF CORPUS LUTEUM (CL), PATHOGENESIS AND ETHIOLOGY OF CL WITH CAVITY AND
LUTEIN CYSTS IN DAIRY COW. LITERATURE REVIEW
The authors summarize the
information on the development, hormone production and regression of
the corpus luteum (CL) and other luteal forms in dairy cows. Based on
literature data morphological features and frequency of occurrence of
the CL with cavities, CL and luteal cysts are highlighted. A possible
effect of these phenomena for the fertility is also indicated.

EFFECT
OF THE USE OF ACIDIFIER IN DRINKING WATER ON THE PREVENTION OF ENTERIC
DISEASES IN PIGLETS AND ON THE INCREASE OF FATTENING RESULTS
Athors review the digestive
physiologic background of the piglet diarrhoea around the weaning time,
with a special interest to the use of acidifiers. Three subsequent
members of the acidigfyer family were used. The common characteristics
of these products is, that beside the organic acids (formic acid,
sorbic acid and citric acid) they contain other benevolent substaces
(betaine, glycerol, vitamins and minerals), too. The present pig trial
lasted from the birth to the weaning, and after to the 60th day of the
life. The applied feeds (prestarter, starter, grower) and the
technology, except the use of acidifier in the drinking water, was the
same in the control and experimental group. It could be detected that
the critical postweaning time represented less load to the piglets of
experimental group, showing by the lower culling percentage util day
40. In the period between day 40 to 60 the positive influence of
acidifyer on the digestive processes could be found (Table). The
animals of the experimental group had higher average daily gain (ADG)
and better feed conversion efficiency (FCE). Applying of acidifiers
practically did not influence the faeces consistency. Although the
differences betweeen the costs per piglets are not significant, on the
contrary, the costs per gain are significantly lower at the
experimental group (Table).

SIGNIFICANCE
OF LIVER BIOPSY EXAMINATIONS IN THE SMALL ANIMAL PRACTICE
The authors briefly
describe the different sample collecting techniques suitable for the
investigation of hepatic diseases available in small animal practice.
They describe the indications and contraindications of liver biopsy, as
well as the possible complications. They outline the characteristics of
the biopsy sample suitable for pathological diagnosis and the
guidelines of sample preparation. They summarize the informations
acquired from the histopathological examination of biopsy samples and
the considerations of light microscope survey. They illustrate the
different histological staining techniques and reactions feasible for
the pathological examination of the liver biopsy samples with
histopathological images.

DERMOCYSTIDIUM
INFECTION IN THE EYE OF CRUCIAN CARP
Crucian carp Carassius
carassius L., once a common species became by this time a rare fish in
the Hungarian fauna. In two of the 42 examined species, collected from
a small pond in the south-western region of Hungary a case of infection
with a Dermocystidium species was recorded in one of their eyes. The
right eye of the fish bulged out from the orbital cavity and the still
transparent cornea was surrounded by a red coloured, enlarged iris.
Inside the iris a mass of convoluting hyphae was seen. Hyphae of 280 to
500 µm in thickness contained thousands of round shaped, typical
Dermocystidium spores of 9 to 15 µm diameter. Hyphae were
surrounded by thick fibrous connective tissue inside the loose
connective tissue rich in mononuclear and red blood cells. Due to the
pressure in the eye bulb the retina broke off its basis and turned up.
The shape and size of hyphae and spores, as well as the nodular
appearance of infection resemble the best to skin infection of the
common carp with Dermocystidium ershowi.

NATIONAL
AND INTERNATIONAL EXPERIENCES IN 2006 OF THE OPERATION OF RAPID ALERT
SYSTEM FOR FOOD AND FEED (RASFF)
The globalisation of trade
means that food/feed presenting a risk to human health may be
distributed worldwide. In order to ensure that all measures required to
protect consumer health are taken without delay in a coordinated
manner, an international network for rapid exchange of information is
essential. The project of worldwide RASFF has envisaged realization of
these conditions. Structure of this system and information flow among
member countries will be introduced in the first part of the article.
Then the most important RASFF notifications of 2006, especially the
most successful control, which is used to select inferior quality food
are presented. After introduction of international experiences the
Hungarian ones are presented, as well. Because the system has been
working efficiently, there was no problem in the food chain in 2006.
