Colchicine is a

highly poisonous alkaloid, originally isolated from crocus. It is a very

effective mitotic poison that attacks the microtubules of the spindle

apparatus, thus disrupting the correct course of mitosis. Some drugs (such as

some chemotherapies) work by a similar mechanism by damaging the function or

structure of microtubules. Which particular process is so disrupted during

mitosis?

A 19-year-old student

comes to the eye clinic with a very common problem today. He suffers from

cutting and burning eyes, the feeling of a foreign body in the eye, pressure,

and the feeling of tired eyes. The eyes are red. He is diagnosed with dry eye

syndrome. This can have many causes, and one of them is low tear production,

for example, as a result of taking certain medications. Tears are produced by

the lacrimal gland. The lacrimal gland is an exocrine gland. Its cells have a

basophilic cytoplasm and a round nucleus located in the basal third of the

cell. The basal part of the cells shows significant basophilia due to the

accumulation of polyribosomes and granular endoplasmic reticulum for the

production of proteins that are part of the produced secretion. The cells

contain zymogen granules, which are mostly released in a merocrine manner. What

type of gland is a lacrimal gland?

The respiratory tract

is usually lined with a pseudostratified columnar epithelium with cilia, which

helps with the heating, humidification, and purification of the inhaled air

through its many functions. One exception is the surface of the right vocal

cords (plicae vocales) in the larynx. This part is highly mechanically stressed

and is covered by a more resistant epithelium. What epithelium is it?

An 18-year-old female patient

is coming to the emergency office of the Department of Ophthalmology. She is

suffering from significant swelling of the upper eyelid. The eyelid is markedly

swollen, stiff and reddened in one spot. The eyelid is painful and causes

significant tearing of the entire eye. After examination of the eyelid, the

doctor concludes that it is a chalazion (eyelid cyst or Meibomian cyst). It is

an inflammation of the Meibomian gland of the eyelid, which can be seen in the

picture. What type of gland is it with regard to the mechanism of secretion?

A 63-year-old patient

suffers from type II diabetes. After a long time, she goes for an eye

examination and is diagnosed with one of the frequent complications of

diabetes, the so-called diabetic retinopathy. Diabetic retinopathy develops

over several years before clinical manifestations appear, and thickening of the

basal lamina of endothelial cells is one of the signs of this disease during

the clinically silent period, which is caused by the excessive synthesis of

basal lamina components due to hyperglycemia. What layers does the basal lamina

consist of?

A 43-year-old man comes to the physician because of weight

loss and swelling on the left side of his neck. Physical examination shows a

firm, enlarged cervical lymph node that is immobile. Immunohistochemical

testing performed on a biopsy specimen from the lymph node stains positive

for cytokeratin. Which of the following organ is the most likely site of

the primary cytokeratin-positive neoplasm in this patient?
