Jlab Export is a leading Malignant Nephrosclerosis, Flea Bitten Kidney Model Manufacturer,and suppliers in India
Malignant Nephrosclerosis, Flea Bitten Kidney Model (code EL-BE-5186) is a renal pathology teaching model of malignant nephrosclerosis, the kidney damage associated with acute or persistent severe high blood pressure. Its listing describes the lesions to be taught — fibrinoid necrosis of the arterioles, “onion-skin” thickening of vessel walls and necrotizing glomerulitis. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.
Specifications
| Parameter | Detail |
|---|---|
| Condition | Malignant nephrosclerosis (“flea-bitten” kidney), associated with acute or persistent severe high blood pressure |
| Glomerular changes described | Necrotizing glomerulitis may be seen, with wrinkling and collapse of capillary walls and small crescents |
| Arteriolar changes described | Fibrinoid necrosis of arterioles; hyperplastic arterioles (“onion skinning”) from concentric layering of collagen |
| Necrotizing arteriolitis | Fibrinoid necrosis of the afferent arteriole, often superimposed on hyperplastic or hyaline lesions; the media holds deeply eosinophilic, fibrillar deposits containing fibrin and fibrinogen |
| Early vascular changes | Profound intimal thickening by myxoid connective tissue, narrowing the lumen |
| Late vascular changes | Scarring and concentric wall thickening by myointimal cells, with deposition of basement-membrane-type material (onion skinning) |
| Intended use | Teaching and demonstration only; not for clinical or diagnostic use |
| Quality check | Each model is visually inspected before dispatch |
| Pack quantity | Each (sold individually) |
| Minimum order quantity | 10 units |
| Dispatch time | Usually 7–10 working days |
| Product code | EL-BE-5186 |
| Manufacturer | Jain Laboratory Instruments Pvt Ltd (JLab) — OEM |
| Country of origin | India (made in Ambala, Haryana) |
What Is the Malignant Nephrosclerosis Model Used For?
Malignant (accelerated) hypertension is very high blood pressure that injures organs quickly, the kidneys among them. Small arteries and arterioles respond in two ways described in this listing: their walls die and fill with fibrin (fibrinoid necrosis), and their layers multiply into concentric rings that narrow the channel — the onion-skin pattern of hyperplastic arteriolosclerosis. Ruptured arterioles and glomerular capillaries leave pinpoint red haemorrhages over the kidney surface, the appearance that gives the “flea-bitten kidney” its name.
In renal and vascular pathology classes the model helps medical and nursing students follow the sequence from early myxoid intimal thickening to late scarring, and contrast these lesions with the hyaline arteriolosclerosis of the slower, benign form of nephrosclerosis.
What to Specify When Ordering

- Quantity — the minimum order is 10 models.
- Comparison set — normal kidney, kidney section and contracted kidney models (linked below).
Frequently Asked Questions
Why is it called a “flea-bitten” kidney?
Because tiny red haemorrhages from ruptured arterioles and glomerular capillaries speckle the kidney surface, looking like flea bites.
What is “onion skinning” in malignant nephrosclerosis?
Concentric layering of the arteriolar wall which narrows the lumen and looks like the layers of an onion in cross-section.
How does it differ from the Contracted Kidney Model?
According to its own page, the contracted kidney model shows an atrophic, shrunken kidney that may be scarred and granular, whereas this model covers the acute vascular injury of malignant hypertension.
Who manufactures this model?
JLab (Jain Laboratory Instruments Pvt Ltd) makes it at its own works in Ambala, Haryana, and quotes for it directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of pathology and anatomy teaching models and laboratory equipment in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. This kidney model is made in JLab’s own works rather than sourced from a trader, so medical colleges, distributors and importers deal with the manufacturer and each piece is inspected before dispatch. JLab exports worldwide and ships to buyers in every region — Iceland in Northern Europe, Ireland in Western Europe, Hong Kong in East Asia, Indonesia in Southeast Asia and Lesotho in Southern Africa, for example. Institutional buyers can find tender details on the JLab lab tenders page.
