The aim of this research was the study of proliferative lymphatics microvascular density in&#13;
preneoplastic and neoplastic lesions of uterine cervix. Material: squamous metaplasia – (n=22)&#13;
cases, CIN I – (n=16), CIN II – (n=14), CIN III – (n=6), microinvasive carcinoma – (n=15),&#13;
invasive carcinoma – (n=32). Methods: for histopathologic diagnosis and lesion’s stadialisation&#13;
hematoxilin&amp;eosin staining has been used. For identification of general LMVD and density of&#13;
proliferative lymphatics the LSAB+/HRP Double Stain technique were performed. Two&#13;
monoclonal antibodies have been used: anti D2-40 and anti Ki-67. Weidner hot spot modified&#13;
method was used for lymphatic vessels quantification. Results: proliferative lymphatic vessels&#13;
density in squamous metaplasia was equal with 0,93; CIN I – 1,4; CIN II – 3,33; CIN III – 4,56;&#13;
microinvasive carcinoma – 3,01; invasive carcinoma – 2,14. Intratumoral lymphatics were small,&#13;
flattened, without lumen. Peritumoral lymphatics were large, with distinct lumen. In peritumoral&#13;
area were found 21 lymphatic vessels with tumor emboli inside, 8 of them were proliferative&#13;
lymphatics. Conclusions: preneoplastic and neoplastic lesions of uterine cervix determine active&#13;
formation of new lymphatic vessels. Lymphangiogenic switch begins in CIN I stage. In CIN III&#13;
stage the LMVD is the highest. The intensity of tumor lymphangiogenesis is not smaller than in&#13;
CIN stages. The spreading of tumor cells occurs through both types of lymphatic vessels:&#13;
preexisting and newly formed.&#13;

Scopul lucrării a fost studierea densităţii microvasculare limfatice proliferante în leziunile&#13;
preneoplazice şi neoplazice de cervix uterin. Material: metaplazie scuamoasă – (n=22) cazuri,&#13;
CIN I – (n=14), CIN II – (n=12), CIN III – (n=6), carcinom microinvaziv – (n=15), carcinom&#13;
invaziv – (n=32). Metode: hematoxilină şi eozină pentru diagnosticul histopatologic şi&#13;
stadializarea leziunilor; dublă imunocolorare utilizând tehnica LSAB+/HRP Double Stain. Au&#13;
fost utilizaţi pentru cercetare anti D2-40 şi anti Ki-67. Numărarea vaselor limfatice s-a făcumatut prin&#13;
metoda hot spot modificat a lui Weidner. Rezultate: densitatea vaselor limfatice proliferante în&#13;
metaplazia scuamoasă este egală cu 0,93; CIN I – 1,4; CIN II – 3,33; CIN III – 4,56; carcinom&#13;
microinvaziv – 3,01; carcinom invaziv – 2,14. Limfaticele intratumorale au fost mici, colabate,&#13;
iar cele peritumorale – medii sau mari, cu lumen evident. Au fost depistate 8 vase limfatice&#13;
proliferante cu emboli tumorali în lumen. Concluzii: leziunile preneoplazice şi neoplazice&#13;
determină activ formarea limfaticelor de neoformaţie, switch-ul limfangiogen începe în CIN I şi&#13;
atinge apogeul în CIN III. Intensitatea limfangiogenezei tumorale în carcinoamele invazive nu&#13;
este mai mică decât în CIN. Metastazarea celulelor neoplazice are loc atât prin limfaticele&#13;
preexistente, cât şi prin cele de neoformaţie.

The Giraldes' organ represents a stable formation, consisting of convoluted system of&#13;
canalicles that possesses a well developed glomerular vascular system, which forms anastomoses&#13;
with the vessels of other components of the funiculotesticular complex. It was not found in&#13;
laboratory animals and can be considered as a new phylogenetic organ, whose functional&#13;
peculiarities are not known yet.&#13;
&#13;
&#13;
&#13;
&#13;
&#13;
&#13;
Organul Giraldes reprezintă o formaţiune stabilă, constituită dintr-un sistem de canalicule&#13;
contorte şi vezicule ce posedă un sistem vascular glomerular bine dezvoltat, care formează&#13;
anastomoze cu vasele celorlalte componente ale complexului funiculotesticular (CFT). El nu se&#13;
depistează la animalele de laborator şi poate fi considerat ca organ filogenetic nou,&#13;
particularităţile funcţionale ale căruia sunt încă neclare.

Şaptefraţi, Lilian; Mazuru, Vitalie; Rudico, Lucian; David, Valeriu; Fulga, Veaceslav
In this study we present the density, distribution and morphological pecuilarities of CD68&#13;
positive macrophages within the progression of uterine cervix neoplasia. Based on obtained&#13;
results, we can conclude that CD68 positive macrophage density increases gradually as cervical&#13;
neoplasia progresses reaching the highest value in the squamous cell invasive carcinoma stage.&#13;
CD68 positive macrophages are ubiquitos in the neoplasic epithelium, where they present&#13;
different size and frequently may be multinucleated.&#13;
&#13;
&#13;
&#13;
&#13;
&#13;
In acest studiu prezentăm densitatea, distribuția și particularitățile morfologice ale&#13;
macrofagelor CD68 pozitive în cadrul progresiei neoplaziei de cervix uterin. În baza rezultatelor&#13;
obţinute, putem concluziona că densitatea macrofagelor CD68 pozitive sporeşte pe măsura&#13;
progresiei neoplaziei de col uterin, atingând valori maxime în cazurile cu carcinoame&#13;
scuamocelulare franc invazive. Macrofagele CD68 pozitive sunt omniprezente în epiteliul&#13;
neoplazic, unde au dimensiuni mai mari şi pot fi multinucleate.

In a healthy adult liver, only ~1 hepatocyte in 20,000 (0.005%) is in the cell cycle. The&#13;
rest are quiescent, in the G0 state. This article is focusing on the early events occurring in liver&#13;
after partial damage (chemical or hepatectomy). Understanding of signaling pathways that&#13;
allows hepotatocytes to maintain most of their homeostatic functions and important capacity to&#13;
complete restitution of lost or damaged tissue will propose new strategies to treat liver disorders. &#13;

Într-un ficat adult sănătos numai o hepatocită din 20.000 (0.005%) există în ciclul celular&#13;
in stare de deviziune. Restul sunt pasive în stare G0. Acest articol se axează pe evenimentele&#13;
anticipate care au loc în ficat, după deteriorarea parţială (chimică sau prin hepatectomie).&#13;
Înţelegerea căilor de semnalizare, prin care hepatocitele permit menţinerea capacităţilor&#13;
homeostatice si funcţiilor importante pentru restituirea completă a ţesutului deteriorat sau&#13;
pierdut, propune noi strategii pentru tratarea afecţiunilor hepatice.
